Description
One day I had a random idea while looking at what was once just a prop. I was cycling the action on the 1887 and I loved the movement and how it worked mechanically (who doesn't?) when I got a random thought, "can I make it go bang?" That little bit of curiosity made this into a fun engineering challenge up to the point where I decided to start learning fusion. It took around a weeks worth of procrastination to bring out these parts, a safe, noise making toy.
I would also like to thank the threaded shells it makes it much easier to replace if a pin breaks where the caps sit (linked in original models, I also included the rail for shells.) Keep in mind I made this WITH a safety cap (file included) on the end and I expect it to stay on when this weapon is fired, regardless of the shells being solid with a small vent hole. But feel free to modify these parts improve anything I'd love to see what can be changed. There is one required spring and optional. A required 0.5*5*30mm spring (you may have to stretch this one out a bit its for the firing pin return) and one optional that goes under neath the hammer spring a 0.8*8*10 or 15mm spring.
⚠ DISCLAIMER & SAFETY WARNING
Toy Use Only: This design is intended strictly as a noise-making toy using standard 8 or 12 ring toy caps. It is NOT a firearm and CANNOT fire projectiles.
Use at Your Own Risk: By downloading and printing this file, you agree that you are solely responsible for the safety and legality of your print. I will take no liability for any injuries, damages, or legal issues coming from the use, misuse, or modification of this design.
Safety Gear: Always wear eye protection when operating this toy. Never aim at people, animals, or vehicles even though this weapon CANNOT fire projectiles, this should be standard for any weapon.
Local Laws: Ensure that you can even begin with printing this with all local laws regarding replicas and imitation firearms. A safety cap tip is also given in the download area. (do not fire out in public the original model also states this.)
Print Quality: Safety also depends on print quality and types of filament (NEVER USE SILK FILAMENT ON PARTS THAT HAVE IMPACT). Use correct infill settings especially on the hammer (recommended 40%+) and durable filament like PETG, The filament I used was Creality Hyper PLA. I am not responsible for failures due to poor printing.
Let me know any suggestions and how I did for my very first ever remix! Here's a video of mine firing (im aware of the horrible viewing angle I probably will remake it at some point):
