The remote to my old school Viper alarm system in my car broke and wouldn't stay on the keyring anymore. I didn't want to buy a new one so I designed this shell and transplanted the PCB into it. I designed it in a way which should retain the water resistance of the original housing. It uses four M2 screws and nuts to hold it together.
I printed this in Clear PETg from California Filament with a 0.4mm nozzle and line width.
I recommend printing the top shell vertically, with the top (12 O'clock) touching the build plate and tree supports enabled. I printed the bottom shell flat on the build plate. See the included pictures for example.
As always I have included the .step files in case anyone wants to make changes to better suit their needs.
