Description

Pepperbox Revolver

About this Model

This is a fully functional revolver for 8-shot caps. It is 100% printed from PLA or PETG! No screws, springs or rubber bands are needed. Not even glue. You can simply plug everything together.

I did hundreds of test prints until everything fit without rework. In a normal case, everything should fit without filing.

It has single action and double action.

The drum is removable.

It shoots 6 mm BB or 3D printed bullets, which are included to the print profile.

This is the modified version of my already uploaded revolver: https://makerworld.com/en/models/945572#profileId-916412

This version has an extended cylinder but no barrel. This is how the first historical revolvers were built. It was called a Pepperbox revolver. The projectile can be accelerated longer in the cylinder and the alignment and sealing to the barrel does not matter.
Another important change is the closure of the cylinder. If you use strong caps and projectiles in the original, the caps burst out at the back and block the mechanism. You can see the handling in the video.

Printing and assembly

I have created 2 different print profiles. There is a closed and a ribbed version. The first video shows the handling and shooting, the second shows the assembly in more detail.

Operation

Some force is required to fire the caps and the spring must be under tension. There is a tensioning mechanism in the handle to ensure that the spring force does not slacken. When you are not using the revolver, you should always relax the spring via the mechanism.

The caps you can buy these days are extremely quiet. But you can buy old caps from the 70s on ebay that are much louder! You can also stack the pads from several caps for a stronger effect :)

Very nice design. But i just want to say here that this would be illegal in Germany. Because it uses hot gas to move a projectile it is a real gun according to the laws. Also you could be held accountable for building illegal firearms if you just print it. I know it is stupid in this case, just wanted to warn others that would want to print it.

@itCouldExplode

I'm not sure if you would really get into trouble in practice, but legally it's unfortunately true. Thanks for the warning.

same in Australia

@itCouldExplode

Wow! Wou must have stronger caps then me. Where did you buy those?

@FynnShih

Replying to @itCouldExplode :

its easy to buy in China

@jrgman133

nice print but I live in Canada so I don’t think it’s legal here😭

@Plasma3D

damn me too

@Bobaf3tt

Its a toy you can buy in Canada. I see no issue printing it but you might want to colour the end orange.

@Polaris_s0i

actually it's fine given the speed it goes. Canada allows anything under 500 fps as a toy such as a pellet gun. since he stated in his video it's about 80 m/s or 262.47 fps it's perfectly under the legal limit. as someone else stated color the tip orange to make it visually obvious.

@lulumonkey

This position is too sharp, resulting in a high probability of dumb fire and cannot be fired.

The designer has replied

@itCouldExplode

You mean the pins? I treid some shapes an this one worked best for me.

@lulumonkey

Replying to @itCouldExplode :

Yes, that's it.Like this caps, gunpowder is not evenly loaded

@lulumonkey

Replying to @itCouldExplode :

Perhaps you can try hollow circles, triangles or crosses

Beautiful design, but the front hole is not large enough for the BB to fit through. The openings on the barrel are fine.

(Edited)

The designer has replied

@venomlegend

it is not a bb gun…

Replying to @venomlegend :

Ummm it is...

@itCouldExplode

I'm so sorry, I mixed up two versions during the upload. I uploaded the corrected version earlier, where the hole in the front is big enough. If you don't want to reprint it, you can drill out the hole with a 7 mm drill bit.

Honestly the most well designed print I have ever seen! I love the: intricate little springs, tools to aid assembly and locking the cap, cap with it's little tabs to transfer the force from the hammer to the cap, it's 100 percent 3d printed, nice skeleton design and I especially appreciate the spring detentioner! The only thing which I could think of which may need improvement, is the cap for the barrel. I find it a little difficult to remove after firing. Keep up your good work!

First and foremost I would like to praise the engineering behind this print, its extremely clever and super cool to watch it all come together. That being said, I have had a few issues with the mechanical properties of the cylinder pusher. My first print was entirely out of PLA, and it worked super well for a couple hours, and then all of a sudden the cylinder would no longer rotate and the trigger got jammed. I took it apart and removed the damaged cylinder pusher, which I assumed was the issue, and reprinted it out of PETG (only had the transparent kind on hand atm). Then after a few trigger pulls, that part failed. Not quite sure why it’s failing all of a sudden, but I’m going to try and print it out of ABS and see if it’s better. Additionally, I wish there was a way to secure the bottom seam part of the body, similar to how the muzzle cap holds down the top seam. Other than this, everything is super awesome!!!

so after so further testing, I’ve found that it’s actually not just the cylinder pusher that’s causing the issue, it seems the cylinder latch is hopping over the trigger, and locking the cylinder into place, most likely causing the pusher fails. I’m thinking that maybe a small wall above the latch to keep it connected to the trigger without holding it down too much might be a possible fix

@itCouldExplode

I'm sorry you're having such problems. It could be that the actual problem is that the cylinder latch does not release the cylinder in time. If the pusher then pushes too early, it gets too much counterforce. This is a combination of the tolerances of the trigger, cylinder latch, cylinder, cylinder pusher, housing, etc. Since everything interacts, such problems can unfortunately sometimes occur. Try filing the tip of your cylinder pusher so that it turns the cylinder a little later.

Replying to @itCouldExplode :

thank you for the response! I think you’re right, but I’ve also noticed that the cylinder latch isn’t staying seated on the trigger, is there something to be done about that?

@FynnShih

Excellent, but these two components don't seem to fit together quite right

I've reviewed other models; this should be a curved surface

@user_2498764012

I sanded it with fine-grit sandpaper, but that's not the issue; the mechanism isn't firing

Replying to @user_2498764012 :

You need to enlarge the front holes; otherwise, the printed bullets will not pass through the nozzle of the gun

@thiagoomenezess

Good evening! My mechanism works, except for launching the projectile. In the video I observed that you use this object from the image, however it is not included in the print. Is this really necessary? Is there a file to print this part?

Bro are these fine as firepower let me know

@CriperExplouder

I have tried EURO caps before, REDICULOUSY weak and quiet, the toys for which these are made function is loader then caps. I suggest cheaper Chinese alternatives, they have no regard for safety, horribly unreliable, and are not filled the same way from 1 to 1. But, when they go pop they go Boom. Also, u can manually empty a few unused caps, and repack them with mo chems, for complete disregard of any safety (just be gentle)
