BEHOLD!
This is the most innovative, hi-tech solution for your painting and hobby things!
Designed by a HIGHLY professional team of only me, using the most POWERFUL features that Solidworks can provide, it's here!

So, this is a paint rack for 12 Citadel-sized bottles, I think Tamiya, Humbrol, and others with the same shape will fit well in there. Holders for bottles designed specifically to prevent bottles from falling, preventing unhappy accidents. If you want to print just the paint rack, you'll need to print 3 shelves, 2 walls, and backpiece (with "BASE").

But, for truly ADVANCED users I may humbly propose more features, like a small sideshelf with box for your instruments or bits (or maybe both). For this, you`ll need to print everything with ("B) letter on it and one ("B") paint rack wall, it's slotted for that.

There are also some planned things which I will add a bit later, like brush and instrument holder, one more sideshelf, slotted stand for your miniatures, to make it truly modular, so you can chain-connect different things and make yourself a hobby workplace. And who knows, maybe there will be some more stuff.

Have a great hobby time!

Update log:
04.06.2021 - Added side/backpiece which could be used to chain-connect your paint racks, and it itself serves as a miniature stand, featuring slots for 25mm square and 25/32/40mm round bases. Also, brush and instrument holder piece provided with it, to store your precious brushes and modelling equipment.
More is yet to come!
