Updated: Painters tray with removable cups. Free hanging, and now also with screw in place!!

A paint tray with removable cups for mixing paint. I originally made it for my kids, but it also works for adults :)

The cups are easily printed, and a full set is printed in less than one hour. 

Update 28/01-24: Added a tray and cups with threads. Keeps the cups more secure in the tray. Print these with no more than 0.2mm layer height due to the threads.

Free hanging cups:

• Tray: print upside down.
• Cups: Print upside down

Threaded cups:

• Tray: Print upside down, small layer height (Maximum 0.2mm)
• Cups: Print right side up, small layer height (Maximum 0.2mm)

There is no need to use supports, but a string or two might appear on the threads, depending on how good your printer handles overhangs. Easily fixable in post.
