About this 3D model

Massage hand or back roller fidget. Spins easily and is easily swappable, with a sort of acupuncture feeling without any of the discomfort. All print in place, the handle is extra if you want, its not required though. Simply pull out the additional piece and swap whenever you want, works even without the additional clip in you don't want to print it. It couldn't be any easier, all print in place with no supports, for A1, P1s & X1c profiles. The clip can be inserted and removed easily, silk and brittle filaments not recommended due to the flexibility required.
