I found some shelfs on thingiverse but was not happy with them, so i decided to learn Fusion360 and i'm so happy with my design that i thought i need to share it with you!
you need 7 M3 screws and nuts,
i used plastic drone flightcontroller nuts :) did not have any other M3 nuts.... (works great!)
I used 0.1mm for tolerance to the shower bar and 3.2mm for the screw holes just to be sure.
hope you enjoy it!
(sorry for the bad images)
- 7x M3 screws 10mm and nuts
thats all :)
