These PTX garage door remotes are very common in Australia. It is also common for them to fall apart, especially when stuffed into the pocket of skinny jeans!
Yes, replacements and cheap compatible remotes can be found on eBay but that isn't anywhere near as fun as an evening of Solidworks.
My design has flexible buttons that flex down to interface with the tactile switches on the board.
The case was designed in Solidworks in two halves which snap together and screw closed.
The print was done in ABS on a freebie printer given to my wife by her boss for Xmas a few years back (LOL score!). It's an Up Mini.
