Printable Gun

thingiverse

A recent update has been made to the 3D-printable gun design, including a stronger inner lever and reasonably-sized clamps. The seven STL files are set up for a build platform of 10x10cm; it's crucial to print onto a smooth surface for optimal barrel interior. No support material is needed. The main challenge lies in the mainspring, which requires parallel strands of filament in the spring arms according to your slicer settings (e.g., Skeinforge). Other critical aspects include ensuring proper hole surrounds and setting fill/extra shells to 0 when printing gun_bits. To assemble, start with the trigger mechanism - linking the double outer push rods to filament axles using glue. The trigger mechanism is then inserted into the lower receiver, which can be challenging. Finally, assemble the barrel, stacking guide (with mainspring), and magazine, ensuring ease of disassembly by only gluing the filament pieces to the lower receiver. Enjoy firing the multi-shot, semi-automatic gun with parametrisable aspects such as magazine capacity, barrel length, and caliber, achieving muzzle velocities up to 40Km/h with PLA. However, remember that this is not a firearm and should not be pointed at people or pets, nor used by very small children.
