Owners of the BMW i3 who experienced accidentally unlocking the car, opening the windows, etc...
I made this case for the remote key fob to protect the buttons from being pressed accidentally. The buttons are now encased in a hard shell protected from being pressed either from you pockets or bag.
The case has a curved outside opening to make the key fob snap right in.
Version 2. I may put a hole for a key chain in the design.
You can change the orientation of the print to minimize the support. I printed mine standing up with the narrow end down and wide part up.
Used Fusion 360 in forms to delicately mold a box to its final shape. Then cut deleted one side on the box for the opening.
