The file 'Joy-Con Amatuar 3D Printer Model' is (stl) file type, size is 264.7KB.
Here is a quick controller / grip holder I made for the Switch. Major reason I made it was because the controller it comes with doesn't allow me to use with my joy-cons while they're in their grip covers.
I like the feel of it, but I think I may be able to make a more compact version.
