Razer Hydra DK2 Top Strap Mount

This little ring is a holder for the Razer Hydra that can be mounted on the DK2 head strap.

It will replace my duct tape solution I used in this video:

I printed it on a Printrbot Simple Metal at 0.3mm layer height, 10% infill, no supports

I uploaded hydrav3, which is a slightly taller version to reduce the tilt wobble
