This is a tension relief tool designed to help loosen tight and stiff muscles in the hips, back, and neck.
The cushion should be printed in flexible filament. I used 20% honeycomb infill and 3 perimeters to ensure consistent cushioning in all directions. The core should be PLA, PETG, or any other nonflexible filament to ensure the wheel does not collapse under normal use. I recommend at least 20% infill and 3 walls for the core.
