Inspired by a spool drawer system and paint holder for completely different spools I don't have, I thought I'd retask the dozen or so Prusament spools I do have.
The Prusament spools do come apart, you have to be quite persuasive.
There are 2 options here, you can make 2 shelves from a single spool as each half of the spool will make a platform for the pots, or you can use the second half of the spool as a lid. A second layer can be added by using a joining bolt instead of a foot.
Print a foot and a foot bolt, push the foot through the 'outside' of a spool to the inside and fasten the nut. You can add rubber feet to the bottom for extra grip.
The core and pot layers are dependant on the pots you have available. the 95mm core will suit the Vallejo Air/Colour/Ink bottles that hold 17ml. The 110mm will suite the Vallejo 60ml bottles that are 36mm in diameter and 97mm high.
There is also a short core if you just want to finish off the top layer without adding a full-height core.
Next is the pot layer. the 25mm diameter ones are for the 17ml bottle and 16 of these pots fit around the spool. Why 16? because you can buy 'Valejo starter kits' that contain groups of pains and they come in a pack of 16. You could possibly cram 20 on, but I thought 16 was a good layout.
The 36mm version is suitable for the Vallejo 60ml bottles which are 36mm in diameter. 12 of these are require for a full circle.
36mm does seem to be the limit in termsl fo fitting them on the spol with eth connector, but if you would like a different size/number etc, please add a comment.
I'm new to joint tolerance since my MK3 doesn't need them, my Mini is taxing my brain, I have uploaded some test pieces that have different tolerances so you can see what fits together for your printer. The top face has dots, 1 dot for each 0.05mm of clearance.
The files for the locking puzzle-like plates are named so they show the diameter of the bottles they store (25d for example), the number of parts for a full circle (16n for example), and the tolerance, zero point... etc.
The cores are remarkably sturdy given they are only 2 perimeters think. I have these stacked 5 high so far and there is hardly any wobble on the top layer.
I haven't decided what to do with the space in the middle of the core if not stacking them (or the top layer) I thought about a brush holding cap with some separators, and maybe some flooring on the foot nut... maybe you can remix something? I left the holes hollow for now as I also thought about some colour LEDs down the middle... too many options :)
