CAP Barbell Add-in Shelf

Secured together with two M5*12 machine screws and 2 M5 Nuts.

Print all parts with the flat face facing down, and 2 of the nuts. 

It is strong enough to hold my biggest cat (10lbs) and have tested it with a 20lbs weight.

The reason it's two separate parts for the “hook” and the “shelf” is to be able to print this on the MK4 and for better print stability. Printed with supports enabled on the shelf, 3 perimeter 5% infill.
