It was designed mainly for games that use touchpad free locomotion. Works great with Onward, Pavlov, Arizona Sunshine, etc. I don't think it would work with the silicone covers as it snaps firmly to the plastic body of the vive wand without much flex. The filaments are esun PLA+ and ProtoPasta carbon conductive PLA; both purchased from amazon. I imagine PETG would be a good alternative material for the frame/spring.
