This is a replacement trigger and trigger stop for a Quest 2 trigger (STL files are models for the right controller trigger and stop-- for the left controller mirror them on one axis in your printing software).

These are cleaned up from 3D scans of the parts. I'm a bit surprised they scanned and printed as well as they did. The parts fit fine directly out of my printer (some support material shaving and cleanup, but not much). Depending on your printer and material, the holes for the screws and pivot may need a bit loosening (just turn the point of some sharp tweezers to reem out a bit, or use a tiny drill bit if really necessary).

BE GENTLE AND CAREFUL when opening the controller. The tiny ribbon cable connector connecting the handle part to the main board is delicate. Take note of the trigger assembly-- connecting the stop is pretty straightforward (a single screw). The axle is a bit more complicated. Make sure you note the orientation and the spring placement on the axle/pivot. (I recommend taking some photos when disassembling-- you can refer to mine, but it's good to have your own so you know the shots).

Also take note of the tiny cylindrical magnet orientation. Mine had a small red dot on the side facing toward the trigger. Orientation is critical for proper functionality. See attached "magnet-removal-and-replacement" photo for how I recommend removing and re-inserting the magnet.

I used 0.1 mm layer thickness, cold white PLA at 220C, 1.2mm wall thickness (thicker than default 0.8 mm, for strength), and 20% grid infill. Pretty standard material and settings, and it turned out pretty well.

For disassembly/reassembly you'll need the various Torx/star screwdrivers. Have patience. Happy trigger replacement.
