This handle was designed for the bathroom, for the shower door (hole in the glass 0.8cm). 

A 5mm bolt and two nuts should also be added to the object. 

The main function of this holder is to hang a towel, T-shirt, and anything else in the bathroom that needs hanging.

This project is designed for a 3d printer with settings:

Support: ±25˚
Infill: cubic ±30%

Add light support. During printing, make two pauses to insert the nuts.
