Everyone's Favorite 3D Printed Shotgun.
Beware, this software can literally kill you and others. This isn't one of those bullshit government-mandated warnings. If you blow your hand or face off, I'm going to get very choked up - there could be tears.
Safety precautions and procedures are not fully documented here.
Before you shoot a DIY gun from your hands, test it first. You will need:
- A secure test rig to hold the gun pointed in a safe direction.
- A bulletproof barrier, such as several feet of dirt or very large tree.
- A string long enough to pull the trigger from behind cover.
- At least 5 of the highest pressure cartridges you can find.
You will need to download OpenSCAD to open the files and render them printable.
This project contains more than one gun design; check out the "Configurations" directory for details. Start Here: #Liberator12k Shotgun Configuration
The original #Liberator12k project goal was to design a safe and functional shotgun from readily available parts, assembled with hand tools and no drilling. I broke this no-drill rule twice - when safety demanded it; I created drill-guides to aid in proper hole placement.
That original goal forbids many designs that are still very achievable for anyone with a few power tools. As the project continues to grow, I will be targeting advancing "tech levels", with a strong focus on simplicity and cost.
Tech Level One assumes you have the tools of Tech Level Zero. A "Plus" tech level describes the 'better than minimal' tools for that level.
| Tech Level | Tools |
|---|---|
| Zero | Metal Hacksaw, Metal Files, Drill (hand or power), Hex wrenches |
| Zero Plus | Cutoff Wheel, Bench Grinder, Drill Press, Bolt Cutters |
| One | 12v power supply (battery, charger, 3D printer, or lab supply) |
| One Plus | Lab power supply |
The real "secret sauce" of this project, is the software library I developed during the design process of these guns. I tried a lot of different ideas, and what I came away with, is an OpenSCAD software library chock-full of useful configurable objects.
If you browse through the code, you'll see the project has been grouped into major functional areas:
- Tooling - Printable tools for gun making
- Vitamins - Store-bought parts, nut and bolts, etc.
- Lower - Grip with a simple trigger.
- Upper - Different uppers that work with the lower (maybe).
- Ammo - Printable Ammunition
- Meta - 3D modeling-specific code
- Toys - Things I've tried and thrown away (maybe)
There are more directories than mentioned above, but this should give you a taste of what's in here.
