Made a headband for the Oculus Quest. The headset is a bit front heavy, so this takes a little pressure off of the face with the support of the top of the forehead. I've tried counter weight in the back before, but wanted to move away from that.
Print as shown in the picture with a brim with or without support, at .2mm & 50% infill. You will need 2 six inches long strips of velcro straps.
Also, for more comfort against the head, add a layer from the fuzzy part of velcro adhesive or use a felt adhesive sheet.
Edit (6/4/19): added a slightly fatter, or taller version, for more surface area to distribute the weight. Also fixed the centering of the "QUEST" logo from the earlier version.
