They did the same for the Steam VR motion controllers. We call them the doughnut sticks for fun at the office, but they are really incredible to use. It was a huge blessing for us that Valve included the exact model for us to modify and reskin, because having 1-1 mapping of what you're seeing in the simulation and what you're actually feeling is huge. We did the same with the PlaystationVR Move controllers, which you can see in an image here: https://1.bp.blogspot.com/-TNDizq2W4eY/VvMWu0mcx_I/AAAAAAAAL... This is just a simple material change for now, but we plan on doing design modifications to the mesh data eventually. Likely we would only change the geometry of areas the hands don't touch, like the tracking sphere, so as to keep the player visual/haptic continuity.

Do you have a link to the location of the CAD files for the Vive controllers, or are you talking about OpenVR render models that are obj format and, afaik, not suitable for 3D printing custom, real world, hardware.
