I designed this model after building some rubber band guns out of cardboard. This model only took 48 minutes to print. It is very simple. All you have to do is clean off the support inside the main body, and then insert the pin through the trigger. To load, insert a rubber band on the top of the trigger and then hook it over the notch. To fire, press the trigger. Use gyroid infill because it's the strongest and will provide good strength for the Rubber band gun.

Settings:

0.25mm layer height

15% gyroid infill.

Raft: Yes

Supports: Yes

Do not use TPU!
