HTC Vive Controller Collar Base Gripstop

This should stop your hand from sliding down the grip on the vive controller while playing games that require a lot of fast swings (beat saber is my test).

V2 gives more support, smaller hands?
V1 is the minimal version that works and doesn't touch your hand unless it slides.

Note: safety still applies. The wrist strap is still necessary. This does not replace any other safety. There is a cut out for the wrist strap in both versions.
