HIMI gouache paint lid

UPDATE Feb 2025: I've created a new stackable set of himi paint holders that are far superior to these lids: https://www.printables.com/model/1173245-stacking-tray-for-himi-paints-and-small-parts

I was excited to discover the inexpensive HIMI paint set, but dismayed that apart from suggestions to “don't remove the foil completely”, there was absolutely no way to seal the tubs back up. How was this going to be chucked in a backpack for a hike to somewhere to do a bit of painting?

Since no lids were provided or had been designed, I decided to design this and just start printing one off every time I change filaments. A nice upside is that it's a fantastic test print to ensure the new filament is extruding correctly.

Note that the tray is not designed to accommodate lids (there's actually not enough room for the tub rims themselves), but these are thin enough that overlap seems to not be an issue.
