Mid and Tall Sizes for Expandable Citadel Paint Tray

I loved the original (the multi_small_335mm version), but wanted to have some easier access to short Citadel bottles on 2nd/3rd rows.

Be advised: this is a very quick and dirty remix made in a few minutes in 3d builder by kit-bashing together a few instances of the original model, then tossing in negative volumes to clear out excess. The polygons already don't look great in preview, and it ends up with a couple of small unintended gaps, but nothing that's visible when in use.

Supports everywhere (only necessary for the interior rim); no need to remove them post-printing, as they're not noticeable at all.

This is rough enough that I wouldn't post it without refinement, but a couple of people have asked for it from a posted make, and it worked well enough for me that I also haven't been sufficiently motivated to go import and draft it all in OnShape/Fusion yet. If I clean it up, I'll add a revision to the files here.

Two taller models that snap together with the original citadel bottle model height, but which fit behind and enables tiered storage of the short bottles.
