This is a remix of the Gridfinity Paint Shelf by bigbrisco who graciously shared the Fusion 360 file for his original design.
With the built-in Gridfinity ability to build a tiered shelf, I found both the need for a large stepped paint shelf and the height of the original model excessive. I wanted to print a 1x4 paint shelf (4x being the max that fits on my 220mm print bed) that prints quickly with a minimal amount of material. I may go through and slim this down further...
(Currently looking into standardized riser heights, so I'll probably update this file shortly)
I've attached a photo showing which paints I own fit in the holes, arranged from tight in the left to loose on the right, and don't fits standing in the back looking on in envy.
