Simple and easy to print bicycle helmet hanging hook.

Print time: around 30 mins using PLA - 15% infill 

To install, just put some good quality double sided tape.

Hint: Print with the long side of the hook touching the print bed instead of the back of the hook for maximum strengh, this distributes the weight of the helmet accroos longer layer lines and makes it support heavier loads.

 UPDATE 

A newer, stronger, more beautiful version is available! be sure to check the pictures
