This is a wall (or desk) rack I made for the 4oz Speedball Fabric Screen Printing Ink Starter Set https://www.amazon.com/gp/product/B07GFTHXFV/

Cut outs make it easy to see what is in what slot and saves material. You could probably get away without using supports, but I've attach a picture where I used some just to be safe on my first test print.

I havent got the full 8oz containers yet to see if they are the same diameter, just taller, to know if they would fit (maybe someone can comment). If not I'll be making a redesigned rack for those in the future, although I dont see why scaling this up (if you have the space) wouldn't work as well. I believe this is around 235mm tall so it fits my Ender 3 just fine.

Jars are a tight press fit for security, but if anyone has an issue I have a version with the holes 1mm larger I can upload (or just scale it up slightly.) Mounts to the wall (3 screw holes up top) or can sit on a desk.
