This is a fully 3D printable working model of a .22LR snap-action mechanism, designed for educational and mechanical demonstration purposes. It replicates the internal action and cycling of a .22LR firearm without the need for live ammunition or metal parts. Every component is optimized for standard FDM printers with tolerances that allow smooth movement straight off the print bed.
Features include:
- Realistic trigger and firing pin mechanism
- Functional bolt and snap-action cycling
- Disassemblable parts for easy study and customization
- No support materials needed during printing
