My Quest 3 controller golf adapter is based on Wasyl00's tennis adapter (https://www.printables.com/model/686026-v20-quest-3-table-tennis-adapter/files).

I have modified it to fit my practice golf club, which has a diameter of 27mm and an M8 thread. 

It is currently functional and usable after adjustment in app(in my case golf+)

However, as I am not yet fully proficient with Fusion, the controller's position may sometimes be reversed when fully fixed.

that is why I made second version of profile, It is fliped 180. so if you have issue with the first profile, use newer version. 

I am sharing this in the hopes that someone with more experience can further improve it. I would like to introduce my 3D printing file on an online platform.

PETG or ABS. don't print with PLA. The strength between layer binding is not enough. 

Need M3 and its Nuts, No support needed. In my case, just bind by strap.
