      OP this is an impressive, novel design. bravo. Some thoughts I have for you:
      1. there may be better geometries for the
      printed trigger spring. the present design's
      sharp corner seems like a fracture point.
      look into compliant mechanisms.
      2. printing the barrel around the cartridges is
      clever. those printed barrels are def
      disposable. barrel liners would work for a
      non-disposable design.
      3. I don't trust the 22s to not blow the gun
      apart. be sure to use PLA+ and tie a string
      around the trigger when you test it. you
      may need to bulk up the design.
      4. seems like a real long, mushy pull on that
      trigger. which will frick up the accuracy,
      which is already shitty bc of the short,
      nonrifled, plstic barrels.

              cura and an ender 3 is the entry level / standard.

              prusa + prusa slicer is the next level. no substantial quality improvement except that you are paying more to do less DIY/maintenance.

              bambu + a bambu slicer is gucci tier

              Why not use PETG though? It has better mechanical properties and I can get it for the same price as PLA around here.

              handles temp, uv, and chems better. but very brittle under impact. PLA+/pro is stronger for these purposes. also, PETG is far more annoying to print.

              Awesome design OP I like the single use cylinder, but like others are said the print in place design is not ideal, but more for strength reasons. I'm worried that the first few rounds would weaken the cylinder and allow for layer separation at the back of the chamber. You should print it in two pieces aligned in the y axis to gain more strength, then load the rounds and hold them together with a fastener, like threaded rod and bolt.

              PETG has good properties and is fine for many applications where dimensional rigidity isn't not necessary like furniture or certain frame designs. But it tends to bend and flex more than PLA+, which isn't good for parts that need solid dimensions. That said, someone made a mostly working Glock frame out of TPU, so these concerns might be overblown.

      What's the black thing connecting the "bolt" and the frame? And how do you plan on assembling this into the rest of the gun?
      Totally encasing the catridges (especially from the back) also seems pointless. The rest of the design would(or wouldn't) work just as well if the yellow part was shaped like a traditional revolver cylinder, making loading much easier.
      I also have concerns about the trigger falling out or being impossible to assemble. Unless you print the body in two halves, but then you have accuracy issues.

                So have that be a replaceable plate that you replace as it wears out. The rotating firing pin doesn't need to be the bolt face.

                If the bolt face was made of metal with drilled holes it wouldn't wear much at all. But OP was talking about disposable barrels anyways. It is going to be a disposable gun for the first dozen prototypes as OP works the kinks out.

                PLA+ is cheap at $14/kg or less and the whole build is probably only 200g.

        that thing will explode in your hand, probably without serious injuries since it won't build up much pressure but still it's as stupid as blowing a firecracker in your hand.
        >a certain number of MPa
        you need a chamber that withstands 170 MPa for 22lr, roughly as much as 45 ACP.
        The cylinder needs to be some sort of steel and wall thickness dimensioned according to its tensile strength. You could use mild steel or stainless steel but you will have to make up with thickness, pressure bearing parts in firearm are made with heat treated 42CrMo or similar .

          OP, recommend that you make a basic "derringer" version like the harlot to test your function before printing the multibarrel pepperbox. Just from a time/material standpoint rather than building the full pistol only to learn that you've made a glocknade.

            I've set off 22lr primers by holding the cartridge very near a candle flame before, for a very brief amount of time.
            Granted, that was open flame, but with a printer you're going to be exposing the primer compound to heat for a more significant amount of time.
            Have you tried this before? I really like the idea and honestly want to try running it through my ender, but also don't want to send one through the base and into my floor boards.

    probably gonna get squibbed up if you print the barrel AROUND the cartridge. maybe not if they're cheap plastic barrels but still might cause a pressure spike and blow up the barrel. I like the idea, a revolving hammer system is a cool idea to play with. loading the cylinder mid 3dprint is pretty stupid and you should try to find a better solution. maybe just make the cylinder 2 parts that screw together or something like picrel but with more screws around the cylinder?

      Yeah I think that might be a realistic way to assemble the cylinder. I'll try it out. The idea was to print the barrel such that it is facing downwards so the cartridges are dropped into their chambers and then plastic is printed atop.

        that seems a lot easier than what I had in my mind, thought you were doing it the other way and had to line up the rounds on the base perfectly so it could get printed around. you make me feel like a dumbass it honestly shouldn't have any clearance issues like mentioned before doing it like that.

        Watch out with your slicer settings. It'll probably try to fill the whole barrel in to support the back where it'll touch the case rims.

        You could also try cutting the chamber area that supports the back of the case rims off from the rest of the cylinder model, printing them separately, dropping the rounds in, and plastic welding/fusing the back on. a solder gun kit that would work for something like that costs like $20 on amazon.

You should print it in two pieces aligned in the y axis to gain more strength, then load the rounds and hold them together with a fastener, like threaded rod and bolt.

        PETG has good properties and is fine for many applications where dimensional rigidity isn't not necessary like furniture or certain frame designs. But it tends to bend and flex more than PLA+, which isn't good for parts that need solid dimensions. That said, someone made a mostly working Glock frame out of TPU, so these concerns might be overblown.

        , if you print it it in an orientation that allows you to pause midprint to load the cylinder, that leads to weakness in the direction that the recoil will going through.

          What direction should it be printed in then?

            Layers need to be oriented perpendicular along the direction of stress. Even with a well tuned printer, the layer adhesion tensile strength is almost always the weakest mechanical link in a printed object. While there is a great deal of radial stress in the chambers pushing out, there is also stress from recoil, as equal and opposite to the bullet. If the cylinder is printed vertically (with the chamber in the z-axis facing up and down) to allow for a pause to insert the cartridges, then the weakest strength in the object will also be in the z-axis in tension. While the chamber strength is maximal in y/x for the radial stress of firing, the back of the chamber is very weak and entirely reliant on layer adhesion force + any structure behind the chamber. I think the best strength would be to split the cylinder such that the chamber ahead of the breach is printed in the y-axis to maximize chamber strength, but then the breach is printed vertically in the z-axis, on its edge, so that the layers are perpendicular to the force being exerted on breach, then secured by a metal pin/fastener. This would maximize strength, which will be needed in a printed chamber design.

                lots of designs use composite construction.
                the amigo verde uses a threaded rod running down the length of the receiver to take some stress off the interlayer adhesion.

        You've clearly not tried. Pausing prints is basic now.
        Also PLA+ is a miracle plastic that does everything except resist heat.

        >Pausing prints is basic now.
        NTA but pausing prints was pretty basic even in 2013 lol. Especially when printing via your slicer not SD card. Frick I even resumed a print (albeit by copying and pasting the remaining gcode and pasting the print start/homing process at the start of the gcode above that) in like 2013-14? IIRC I guessed by looking at the amount of lines of gcode my slicer said was read and just copied the next one down; it's been a while since I did that. ReplicatorG 4 lyfe.

    It's cool that you drew something up in CAD but have you actually done any engineering, testing, R&D? Have you even prototyped this yet? If that cylinder is fully printed, will it come anywhere near withstanding 10 consecutive shots before shattering?

    Idea for sights:
    Have the latch on top have a square notch in it. Extend the end of the latch all the way out to the end of the barrel cylinders, and put a post on top of it.
    So your latch and your sights are the same piece.

      also what the diameter of the yellow barrelmag? it would be an advantage to aim for some standard size like a soda can, because then you could use any drink holster as an ammo holster lost of premade gear carry and concealment options.

        If you use the space for an integrated suppressor?
        Performance won't be great (many holes) if you use the center space as chamber for all but considering it's inaccurate anyway putting TPU wipes on them might work well.
        If your local legislation won't cause a problem ..

      Could probably do that but might want to thicken it a bit if so.

    You'd need an empty chamber so it doesn't go off while carrying it or even if you frick up while assembling it.

    Lots of "RONI" designs to encase your pistol in a supporting frame with mounting for a brace. But not much at all to build something with an open top so I can use my pistol sights and not worry about a changing zero between mounting and unmounting.

    Also I really want to build a 3011.

    Walls on the frame look too thin. You need to remember you're likely gonna print this in PLA. The frame is likely gonna warp and crack after a few shots even if the barrels survive. I recommend that the walls surrounding the rotating striker mechanism to be at least 6.4mm thick. I also recommend checking out other 3D printed designs like the Harlot by Black Lotus Coalition if you want to add a breach or use a barrel liner.

    Should it have some relief ports to make sure it can fail-safe if the barrels aren't strong enough to handle the pressure? You might also want more material between each barrel so that if the plastic around one barrel bulges it doesn't create obstructions in neighbouring barrels.

      Not OP but ports all around the cylinder would act as a perforation. If the barrel blows up, it will likely be along the layers anyway.
