Headphone holder - TrackIR friendly - parametric

I tried to have very small overhand, my cheap printer was happy to print it without any support. 0.3mm layers, but probably all the settings, including infil is't up to everybody. Mounts on a desktop tower / wall pretty well. The holes are through all so the screws can go either direction (in case of desktop they will go from inside, in case of wall mount they will go from outside). And there is enough spacing for the headphones to sit straight down.

Contain A slit in the middle in case the headphone has pasive trackIR clip attached. Mostly designed for Microsoft LifeChat LX-3000, but could work with other phones too.
