This is great. Looks a tad big, would be good to know it's measurements
The main missing thing from this is waterproof design. Doesn't need to survive immersion (unless you have a Turkish Van) but it will get damp as the cat pushes through wet undergrowth or if the cat gets caught by a sudden shower.
Main things would be an ip67 rated usb connector, and a channel for rubber seal along the case join.
(edited to add)
From the STL, this is much bigger than a tabcat. The tabcat is 23x33x12mm in its silicone cover. This is ~27x60x13mm.
Another handy feaure of the tabcat (although not essential) is a beeper.
