Print Info

The clip modules should be printed at 2 walls, 10% gyroid infill to be both strong (enough), and light (ish).

The sear, ram, puller, sealer, spring cup, and T pull should all be printed at 5 walls, 100% infill.

The rest of the blaster can be printed at 3 or 4 walls, 20% infill. GYROID INFILL IS BEST.

Print 4x of the "Bracket" part.

Assembly

Assembly guide:

If your cam arm extremely wobbly on the side, print the tighter version. A bit of wobble is normal.
