This is a motor shim plate for most AEG's. It has a rim around the edge to help keep it in place. It takes about 1 minute to print. I put one in my cousin's AEG with a v2 gearbox, it's been in there a while and it hasn't given us any trouble yet. I hope this Is within the rules of thingiverse. Settings: Use %100 infill, 1 perimeter ( vertical shells), all speed settings fairly slow, and the smallest nozzle you have (.5mm worked fine for me). I would recommend .2mm or less layer height. Install were the old shim plate was with the rim facing the set screw. Remember to adjust the set screw to achieve correct motor height!
