Backpod Clone

I am trying to reverse my neck hump, forward head posture and find relief from my costochondritis. I've read about the Backpod and wanted to try it, however it wasn't available in my country. The shape seemed simple enough and I saw another person 3d printed one on Reddit so I wanted to give it a shot.

Use it at your own risk. 

I printed with PLA, 6 walls, 25% adaptive cubic infill and it's rock solid. 

The 1x scale is the original dimensions (20cm length, 12cm width and around 6cm height at the highest point).
