The key ring slot on my wife's OEM remote start case broke so I modeled this up. I printed this out of Jessie Galaxy Black PETG with a 0.4 nozzle, 0.15 layer height.

Support is needed under the key ring slot only. After trial and error I recommend that you use paint on supports and leave a slight gap between the main body of the case and the start of the supports.

Update: 1/10/2023

Updated model to level the internal supports for the PCB and enlarge the catches to better hold the case together.
