The key fob on my Dodge has buttons that stand proud by 0.5 mm. This is a problem when I put them in my pocket, becuase I've been able to lock and unlock my car acidentaly. To remidy this, I made this cover to make the buttons recessed and protected. This is version 2 of this design.
This does not require supports, as you drop the key fob in and the fob itself supports the top part of the print.
