You will need:
- One 1/4"-20 x 4" Hex Bolt
- Two 1/4" x 1.5" Fender Washers
- One 1/4"-20 Wing Nut
- One 'Base'
- Two 'Top'
I printed mine with 30% infill.
The whole thing is pretty sturdy and seems to work, however there are a lot of improvements to be made and I've reached the end of my ability to 3D model. A couple of problems are that the blades in game intersect and cause the controllers to rumble always, and the length of the blade is a bit shorter than normal.
It is a LOT of fun to use this, so if you can you should give it a go
