Airsoft AK-47 Redesigned Selector Gear

thingiverse

I was fed up with that annoying screw coming loose all the time, so I decided to redesign the gear arm to eliminate the rotational force that was causing it to loosen up. After 14 failed design attempts, I finally came up with one that works - at least in my gun. WARNING: You'll need to use a 1/4" drill bit to remove the gearbox's screw hole, and once you do that, there's no going back. Note: There is some support around the hole for the trigger lock that will need to be cut off. Print Settings: Printer: Wanhao I3 Rafts: Doesn't Matter Supports: Yes Resolution: 0.1 Infill: 100 Notes: I printed it in PETG, but a harder plastic would be even better.
