NIH 3D
This design was optimized for comfort and reduced print time to increase production volume using crowd-sourced printing. This can be printed on coarse print settings down to 30% infill and produce a durable, comfortable device. The elliptical cross-section was designed to reduce pressure points (found on some other designs) thereby eliminating the need for additional padding or foam which can be unsanitary, and increase cost & assembly complexity. This file is free for community use. I hope it helps!
