My Genie outdoor wall-mounted Garage Door Opener battery door broke a long time ago, and this design fits fairly well.Sorry the pictures are a bit dark.The clip part at the top is not perfect, but I'm too lazy to fix it further.  :)Original Tinkercad design here: https://www.tinkercad.com/things/gU2pRBYapbQ-genie-outside-garage-door-opener-battery-cover
