This is a very naive rework of "Modular Paint Rack for 25-35-50 mm Sized Bottles" by Empiricus. The original requires a 300mm print bed, so I wanted to try to make something smaller to fit more printers. I sized it down to approximately 200mm x 200mm.
This is just a first attempt -- literally all I did was cut chunks out of the middle of the parts and then stick the remaining pieces together. To assemble this you will also need "Bridge1.stl" and "Bridge2.stl" from the original -- I didn't modify them so I didn't bother including them.
I haven't tried printing and assembling this yet, so there's a good chance it won't work. But hopefully it does!
There are two versions of the "35mm" file. When I chopped up that one the remaining pieces didn't connect very well. "35mm.stl" is the chopped-and-merged version; "35mm_extra_connectors.stl" has some extra material added to make the connections more solid. But it looks janky. Well, they both do. Did I mention this is just a quick-and-dirty first attempt?
