One of my favorite models to print. Just print Case Front, Case Back, 2 Buttons, 2 Pins, 1 Toggle, 1 Spring (Print Spring with 100% infill. Ideally, the filament path should run the length of the spring.) and snap them together.

NOTE: This is NOT my model it is just one of my favorite models that I reposted here on Nexprint I changed nothing please go check out https://www.thingiverse.com/thing:4906027
