I have a Patreon page! :)
A geometric curiosity in which to keep your tools, brushes, pens, pencils, hopes and dreams! You might choose to print just the outside, but of course if you pick it up all your stuff will fall out the bottom, so bear that in mind. Anyway, you should print the insert so that you can make cool colour combinations and astound your friends with your well-honed sense of style.
Also, you might like the Mind Caddy, which is an angular, brainy kind of thing: https://www.myminifactory.com/object/3d-print-101358
