Steering wheel pad/cushion

My thumbs were sore from gripping the wheel so I decided to make these inserts. Most steering wheels have padding along the spoke so there is no need. My wheel (TC racing) is a flat 5mm metal strip that drops 20 degrees, this digs into your thumbs while racing and I got tired of padding it with foam. First, I printed this in pla and it looked great and helped distribute the pressure. I never printed a flexible part before so I figured I would try it on this project with some ninjaflex tpu? ma
