A friend asked me to print this for his HTC Vive, I thought it took way to long to print and used too much plastic so I made it a bit lighter and quicker to print. The strength feels great with 20% of the plastic used (25% infill) compared to the original design. It's not been tested yet with the actual headset, so please be patient until my good friend has tested this out.
Or print it and test it if you want. I've printed it both in PLA as well as PETG, I think the PETG version will hold up best but the PLA version feels strong as well.
Holes made for 4 x M5 screws, you probably just need to screws but that's up to you.
