Double indent Pain sensory fidget

A set of 8 Pain sensory fidgets. This with a double end indent. The edit came about with my recent back issues and my nervous system going haywire. I like the feel of an indent so decided to make it a double indent. i would advise to print with a small support on the indent that iOS to the build plate. Once removed add a little heat just to smooth the inside slightly. 0.2 layer. 15% infill.
