This is a simple frame I made based on 16mm tube (From a clothes prop) to hold the controllers from a Quest 2 in a 2 handed rifle formation. Rather than use magnets to hold the controllers on I opted to hold them in place when I use it, that way I could drop the frame easily to throw a grenade. I printed it in PLA and made the holes a tight fit on the tube.
It would be best to print one part as a test for size before printing them all out.
No supports required and the parts all slide on the tube with only two cuts for the stock. I made these 130mm and 150mm long.
The “grips” actually came from this Thingiverse model and I just chopped them down a bit and added the block to the bottom.

I have included an end piece that is not shown in the photo.
The author marked this model as their own original creation.
