Tile Mate 2022 replacement body.

I was looking for a replacement body for my Tile Mate 2022. With non replaceable batteries, I've been cutting them open to replace the battery and after a c ouple battery replacements.... Well the case was no longer holding up.

It's made in TinkerCad, and I'm not a very good designer, so please improve on it if you can. I've tried to incorporate brackets to keep the motherboard from moving in the case. The top is 0.5mm thick and has a protrusion on the inside to click the button on the tile.

I printed this with a .4mm nozzle using .16mm layer height.
