Designed to fit to snugly embrace the metal bar (or any other kind of bar, as long as it is 16mm in diameter), this hook guarantees stability and can easily bear the load of hefty coats. 

I have used PLA with theses settings: 0.28Lh, 100% infill, and 6 perimeters.

Printed multiples for my use. These hooks have endured months of use without showing any signs of deformation or wear, attesting to their enduring strength.
