The wires for the controller like to break right where they meet the case. Unfortunately the case is pretty hard to get apart without wreaking it. I made a new case which reuses all the internals from the old controller. I found printing in PLA not strong enough but PETG works well.

There are 5 holes for M3x12 bolts to hold the two halves together. Using only 3 seems to be enough in my testing though. You will need a single M2x12 that goes through the trigger pivot.

Wire is 22awg.

Infill isn't important as it will all print solid anyway.

I took a picture of the old controller, imported it as a canvas into fusion 360 then traced it. With a set of calipers I placed all the stand ups at the right location and height. I had to do a few versions with lots of push/pulls to dial all the placement right.
