ProSaber
How do I install my Index controllers in the controllers mounts?
How do I install my PS VR2 controllers in the controllers mounts?
Can I make a ProSaber out of my MagTube without needing to buy anything?
Technically yes. But we do advise against making a ProSaber with magnetic controller mounts. Since you are not holding the controllers in your hand while using a ProSaber, the risk of them flying off and hit a wall is too great.
You can contact our support to ask for the screw needed to fasten the controller mounts.
If you already own fastened controller mounts, you can go ahead, though. Just follow the mounting instruction.
