Motorcycle Helmet Hook (head shaped, kind of)

I needed a way to keep my helmet at home and at work secure, and keep from getting knocked on the ground.

I measured the interior of my helmet and came up with this custom shape. It mimics the back of your skull. Supports the helmet by the back of the interior. I wanted a unique mounting solution, and I think this may be it. 

Helmet basically sits on this on the wall with visor section down towards the floor.

Printing setup.
