This is a wall mount for the Vive head mounted display (HMD). It was designed to support the Vive on its hard plastic parts to protect the soft foam from too much compression. It fits both the narrow and wide face cushion with any IPD and face distance setting.
The small triangle shaped compartment allows you to store your cleaning cloth or other accessories and it also saves some material during prints.
There is a new smaller version available that should make the model printable on more printers. (135mm x 116mm x 147mm)
Make sure that this mount is screwed to the wall very well and ensure that no one can step on the Vive's cable to avoid damage to your HMD. I am not responsible for any damage that this mount may do to your HMD.
