How it fits the arm
Needs side guards, also specifically designed points for catching blades because currently it's just sliding everything into your forearm, genius.
Also this, thumb tendons seem vulnerable. Maybe you could fit a thick leather glove onto it?
What is this fricking moronation?
Your fat will do more to protect you than that shitty print OP
Needs metal
You’re fat
You know that old saying “if you’re fat, you’re probably going to die”. That fits here as well. Your lack of stamina, size, and overall poor health should be just as if not more of a priority then “hand shields” for make believe combat that you’ll never actually take part in because no one is concerned by a fat loser with a plastic towel hook for a “shield”. I promise you you’re better of losing weight before you start trying “master the blade” lmao.
Works like a less obtrusive spiked pavise
There's a growing number of cases of physical violence in our society. Attacks with hand weapons are becoming more and more prevalent and for many, guns may not be a viable solution.
I'm looking at ancient examples of self defense tools that can help us keep up with the maniacs with machetes roaming our streets.
The way you'd use this punch shield is similar to how we used bucklers in the past.
Not so much like a big shield you can hide behind (IE: Scutum or kite shield), but a more active form of defense where the shield allows you to use your forward hand to intercept a weapon or parry strikes.
>and for many, guns may not be a viable solution
Why? The justification for physically assaulting someone is exactly the same as the justification for shooting someone dead.
Finally some cool /k/ontent.
I'm interested, go on.
I remember seeing something like this on a Zaku in Gundam
Yes the Zaku was the inspiration! good eye!
Thank you!
Yes the side guards protect your hand from the stray knife slash.
The raised lip at the end was to deflect slashes away from the forearm and elbow.
The shield is also crosshatched to provide a catching surface for blade tips and edges. A thrust would likely embed into the hatch and not slide to other parts of your body.
based /m/an
test it on a punching or something
Version 2 is in design phase.
I've removed the raised cones. They didn't add to any defensive purpose and replaced them with 1mm cross hatching, to catch knife blades and tips.
I've added spikes to the front as a blade catching tool.
Also increased the overall size and ergonomics of the handle.
Forgot the image, oops.
In terms of usage, I would suggest a front hand extended stance. See image of Joe Louis's usual Blackburn Crouch stance.
The shield covers more of area the farther it is from your body and Joe Louis' stance allows your major vitals (heart, gut, lungs, throat) to be covered.
Your rear hand is also protected and ready to strike, grapple or fight back with your own weapon.
To use the punch shield successfully, however, you must use it actively. Use it to actively disrupt the opponents weapon. Get it in the way, push it out of position, etc.
I would not suggest you punch with it, however, since that will leave you open. The hard plastic can also cause extensive damage to your enemy if you hit him in the face.
This is a pretty good idea of how to keep your shielded arm active.
why not just make it a box with an open end for your arm bro?
less flexibility and more difficulty in putting it on. The current form allows you to adjust the grip much easier to fit different purposes.
Gun loses some effectiveness in a knife fight under 21 feet according to some experts.
Also, a lot of people can't brandish a gun in all circumstances where knives could be used against them.
>Gun loses some effectiveness in a knife fight
but a gun remains more effective than a knife in a knife fight
Lots of people live in places where you can't carry guns all the time.
Lots of people also don't want to be associated with mass shooting culture.
>id rather viciously cut and stab a person repeatedly while they scream out in pain and i get coated in blood, emerging from the scuffle covered in viscera, injured by the asaillant's struggle to stay alive, and sometimes also equally wounded with similar cuts to vital organs. I wouldn't carry a gun and just verbally de-escalate the situation. I dont want to look like a maniac.

Seems like machetes are being used more and more in random attacks.
So shoot the motherfrickers carrying machetes
Criminals don't follow the law. They'll cut you to pieces with a machete. Meanwhile in the UK and Canada, you generally can't (legally) use a gun for self defense. Instead of trying to 3D print some meme gauntlets I'd be moving to a country that supports an individual's right to self defense.
>its illegal to dice a person alive with a machete
>people do it anyway
>law doesnt stop them
>man can behead someone in the streets and leave without any problem, never get caught.
>its illegal to carry a gun
>FRICKING DO IT ANYWAY
>shoot a guy trying to behead you
>literally nothing stopping you from just leaving
>just fricking leave. Walking away is free. Whats the worst they can do? arrest you? fricking leave.
>>its illegal to carry a gun
DO IT ANYWAY
A lot of you folks larp as special forces gunslingers. None of you guys could actually draw faster enough to stop a guy with a knife.
Also, if your only tool is a gun, every problem is going to look like a 12 year old school child.
Criminals who are smart plan on how to get away with their crime
You can't plan on when you will need to defend yourself and ensure you get away without getting caught
yeah, nothing is going to save you from a well planned ambush. Only way to stop that from happening is to not piss off those type of criminals to begin with.
This tool seems like it would be good for the random street violence we're starting to see. But only if you're weird enough to not give a shit about carrying this thing with you everywhere.
>Lots of people also don't want to be associated with mass shooting culture.
What a dumb homosexual thing to be worried about.
>mass shooting culture
If you didn't know OP was an alt left brainwashed euro before, you know now.
This is one of the most homosexual things I’ve ever read on this board. Actually have a nice day.
Anyone have the video of the panyfa trying to stab some guy and getting shot, while the camera guy cries for the police?
it loses effectiveness because stupid fat zogbot cops didn't practice defensive shooting from the holster and most still don't
in an ambush, by a person who knows what they are doing with a blade, you're not going to know there's a blade at all until after the attack has happened
the raised cones are WAY more likely to help than any "cross hatching" lmao. just make them cylinders, not cones
>weabshit was the inspiration
makes sense, do the cross hatching, i hope you get cut
What a negative nancy. You fellas buy every piece of shit gun accessory they come out with
>>inb4 bump stocks lol
and you're shitting on this piece of homegrown genius?
Wouldn't this fall under "brass knuckle" laws?
In Canada, no.
In Canada, brass knuckles, or any similar devices made of metal, are listed as prohibited weapons;[14] possession of such weapon is a criminal offence under the Criminal Code.[15] Plastic knuckles have been determined to be legal in Canada.[16] Similar legislation has been instituted in Russia and Australia
Also, this isn't meant to punch, really. It's meant to block and parry blades like a shield.
Bucklers are legal throughout the US and Canada.
>bucklers are legal
You better not be lying to me. I’m going to start carrying this bad boy when I go out. If I get arrested I’m telling the cops some anon told me it was okay.
Just tell them it is a Pakistani rice bowl
put it on your head and tell them it's a hat
looks good but it needs wrist support it looks like you would break your wrist the moment you hit some one with it
also what happens when the plastic evetually breaks would it go into your hand?
It's held with the wrist able to hinge. The shield face doesn't sit against your forearm but can change angle with your wrist.
It can also be held with the shield face in your palms direction if you're used to catching punches on boxing mitts.
If you're getting repeatedly slashed with a heavy blade, this thing will obviously get some damage but the plastic is tough rather than brittle so it won't shatter.
i'm pretty sure that's a lego separator bro
Neat. Can you put a knife in a vise and punch it for demonstrative purposes?
I printed it with 50% infill at 1.2 mm layer widths using PETG. It feels stronger than one of those plastic cutting boards you can get at a kitchen goods store.
The purpose, though, is not to take a full on thrust or slash even though it could survive with minimal damage. The purpose of the shield, with its unique design, is to allow the wielder to active defend himself by smothering the attacker's angles of attack to provide opportunities to counter attack.
Holy shit if you got attacked by someone with a knife you would die, they might get a black eye.
Just tried working some rounds on the heavy bag with this thing. The corners are the deadly parts for punching.
If a corner hits an eye, it's popping an eyeball out.
You can basically throw a jab at 50% power and expect damage.
You'll still die because you're a fricking moronic cuck.
Go find me a boxing match where someone doesn't get touched.
Now imagine the one doing the touching was stabbing you each time.
Not to mention 60% of all agrivatged assaults have 2 or more people.
YOU WILL DIE
I find that notion quite amusing, but I hope honest, good, non cucks lurking don't follow you.
the goal is not to have a boxing match with a knife fighter. The goal is give you options to parry a knife attack so it doesn't go into your hand.
>I will confront a knife attacker with my plastic wrist guard and just punch the knife if he attacks
Sounds like a fantastic way to end up with a knife in your belly
I would probably back away from an attacker while using the shield to maintain distance between the two of us.
Parrying isn't all that hard, if you have some boxing experience. The key is to do it with minimal movement so you don't get out of position with a feint.
Yes likely a problem that will be solved with flared rim to deflect. Pic related.
Metal is possible and easy to attach diamond plate or something. Plywood is also strong enough to block most knife and axe attacks.
Just finished testing it out with some eskrima and knife fighting dudes. We're all using rattan sticks and foam knife sparring gear.
The shield works well as an active defense. You're using it to jam the opponent's weapon before they reach full extension and also parrying attacks to your vitals.
Doesn't work well as passive defense, as predicted as the shield face is small.
Did some testing with sharp blades, just for durability. Didn't spar with live blades because we're not stupid. Heavy slashes with a bone cleaver chipped the rim somewhat. Hunting knives leave scratches. The cross hatching helped to keep the blade "stuck" when it hits, stopping sliding.
Again, works like a buckler. Everyone who tried it says it would be better to have it than not if fighting against a knife wielder.
This stance seems to work the best

bruce lee's own text has his front hand down to protect the groin.
>Parrying isn't all that hard, if you have some boxing experience.
If you had any boxing experience you would know you'd die trying this with a knife.
Kek.
Go take a boxing class, and try to parry a punch.
Then remind yourself every one that hits you is a stab wound.
I do and I spar regularly. It's easy to parry punches if your guard is up and you know how to manage distance.
FakeNgay
>moron underage euroBlack person thinks plastic boxes on hands would keep you from being stabbed
Well I guess it's a good thing once boxers put on boxing gloves they are impossible to punch.
>3d Printed a less than lethal hand shield for the purpose of personal defense against knives, machetes, and other hand weapons
if only there existed a mass produced lethal hand cannon made for the purpose of personal defense against knives, machetes, and other hand weapons...
when doing Security I like to wear a hard hat for similar possible use, plus harder to sucker punch a guy in HH, and HH protects skull from bottles thrown from behind, etc, plus carries big head lamp for hands free "lights where I look". 🙂
but then I don't get to LARP as some LEGO cyborg 🙁
Your heart is in the right place but unless you're making something that just looks cool you're dumb
This shit is less effective than coldsteel mallninja punchknfie shit
Yeah, I'll be making it tactical black in my next version. I'm just prototyping now so I can test this with my bjj/kickboxing buddies.
Let's be honest here anon, if you're going to roll up to the protests with a 3D printed glove you might as well print a full suit of armor to protect yourself.
If you're going to a protest with any weapon, you're an idiot. See: Kyle Rittenhouse
>just let 200 people stomp you to death
Neat idea if I were you I would add a lip on the top of it so you can slide some thin sheet metal or something into it so it’s not just a giant hunk of plastic.
OP's final form
underrated
OP it's a nice little print, but please don't try to use it as an actual self-defence weapon. It will be markedly inferior to just about anything and probably get you killed.
Look out guys, he's armed with legos
As someone who sexually identifies as a Gelgoog Marine variant I want one.
OP reinvented hand trux
>oh, you drew a knife? Just give me a minute to get my giant autism Lego dusters from my backpack
>oh no you stabbed me
Alternatively
>alright buddy prepare to get parried
>oh frick you just barreled into me and now I have a knife in my gut, I thought we agreed to stay at arm's length like boxers?
Lol are you a robot who can't adapt to changing scenarios?
Christ you gun nuts are dumb
Hey it's your life, conscience demands trying to stop someone from believing their wrist guard will effectively deter a knife
butthurt
a giant, bulky, plastic and hard to carry or conceal wristguard.
Yeah that's a problem
Open carry is only acceptable with a gun because you're too afraid to laugh
looks gay just use a padlock homosexual
so…….how are you going to edc that thing?
Zaku
That's some weird lego brick.
Interesting concept. I'd definitely change the print orientation to the side so that the layer lines follow the whole shield. As it is, the bottom is very likely to snap off if force is applied. You can also implement some threaded rods to hold the layers in compression sideways and it will be far stronger.
Hey this is really great advice.
Especially with regards to the layer lines.
I was planning on hardening the whole apparatus by doing the salt bake, which would remelt the plastic into a single unit.
Even still, you are printing it in the weakest orientation possible. It needs to be printed on its side or it will break into pieces with the first punch.
That's not exactly true since I've done a few rounds with it on the heavy bag and it's sturdy.
Also, tested it with rattan and knives in sparring. It's taken quite a few heavy hits with only chipping from a meat cleaver test.
I went ahead and made a model based on the photos and it seems like it'll fit on an ender 3 bed when sideways. I'm not sure what your measurements are but it can probably be modified to fit if it's an issue. The salt bake sounds like a good idea to me. It just seems like a lot of effort since the item is pretty large and you'll need a shitload of salt.
Wow this is awesome, friend
Thank you!
Anytime, man! I love helping with personal projects like these.
A chainmail glove with lade catching hooks on the palm would be better. Just grab the blade and twist it out if his hand.
That's hard to make for most people.
too bad you cant get the layers the other way. i see its too long for your build plate... i know how that goes
Yeah i'm printing it with vertically. I'm using a 0.8 nozzle which seems to help with strength.
The whole thing seems sturdy enough for the time being.
nylon might give you better impact resistance
If you want to make more, make a mold and cast it instead of printing off another one
