Needed some hooks for my sliding glass shower door which is 6mm thick. I made this to be 6.1mm thick and it fits perfect. 4mm walls all the way around allows for perfect clearance between my shower doors and the frame.
Supports were needed and I printed this on its side for better layer adhesion. 1 hook took 36 minutes & 2 hooks took just 46 minutes at .2 and all other normal settings other than the following settings: 3 walls, 15% infill w/adaptive cubic pattern. Printed in PLA to start for prototyping but may print in PETG after I see how these hold up.
