Breaker bar wall holder

Print without supports but give it a few extra perimeters for strength. 

The head of the breaker bar just sits nice and securely in the pocket

Designed to mount with a single screw to a wall. I'd advice against using anything weaker like double sided tape, it's a heavy chunk of steel you're hanging

This is the exact breaker bar I have, it's great quality and doesn't cost a lot:
