This is a simple plate for mounting your Vive base station (Lighthouse) on a tripod.
There are three models available: A 45 degree, a 37.5 degree and 30 degree version. Chose the one suitable for your setup.
You will have to source a 1/4" Screw with 12mm length to mount the base station and a nut or another screw to mount the plate on top of your tripod. If you use a tripod with a very short screw, there's a slim version available.
If your printer can't handle 45/30 degree overhangs you will have to print this model with support.
