About this 3D model

This is just a simple adapter plate for the Vive n Chill to fit the Valve Index a little bit better. The face of the Index is nearly flat in that area. I made the bottom flat for better printing. You need a brass insert (M3) which you can push in with a soldering iron. You can use the original screws. I also added a version where you do not need the inserts. I have not tested that version yet. (If it is not working for you please let me know and I can change it.)
