Storage rack system for Hobby paints

This is a paint rack/storage system for hobby and miniature paints. The paint bottles are held in interchangable trays that can be placed on the shelves. I created a few variations: parts tagged with "26mm" fit paint bottles of 26mm and smaller.  This includes Scale75, Vallejo, Army Painter, Warcolours, OLD monument/pro-acryl, Reaper, Turbodork, etc (nominal size of bottle holders is 26.5mm).  Holders hold 8 paints per tray. Parts tagged "GW" fit the wider pots from Games Workshop, P3, cote
