Easy to print, snap together case for the TV-B-Gone kit (https://www.tvbgone.com/shop/tv-b-gone-kit-universal-build-tv-b-gone-kit/).
This fits mine perfectly, but I've also include the Fusion 360 file if you want to make tweaks (sorry for the weird translation stuff at the end of the timeline ;-).
When taping the board to the battery pack I left 7mm between the back edge of the PCB (side with green LED) and the back of the battery case. This leaves the LED's only slightly hanging over the other side of the battery pack so they are mostly inside of the case. Also have to make sure the capacitor is lying horizontally on the board, not vertically, to fit in this case.
Printed 100% infill.
.2mm quality.
PLA works fine.
3mf file included.
