Airsoft fire selector

This is an AR selector switch for airsoft. The selector can either be fastened using a screw, or you can print the version with a clip

I finally finished a working version of the selector switch! it only takes two pieces, no screws ball bearings, or springs. There is a small support structure on the inside so that the selector can be printed upside down, this must be broken by pressing in on the spring backed nub once printed. The two pieces snap together and hold onto the lower receiver, they can even be released by poking a small tool into the hole where a screw would normally have gone and popping them apart. It can take quite a bit of force to clip the two parts together, but they should eventually snap together. If you have any questions or need me to make slight changes to the files, just let me know.
The final form is selector V.12 and plate V.10

V.4 and V.5 take a ball bearing and spring and are screwed together

V.8 and V.5 use a compliant mechanism and are screwed t
