Dropper Bottle Paint Racks

 

This is a stackable shelf module, 190mm wide, designed to fit standard 25mm diameter dropper bottles such as those used by Vallejo or AK Interactive.

It is not a complete one-step shelving solution. The modules will need to be glued together, and the whole set will need to be secured to a base-plate of some kind to keep it from tipping over. Depending on the number of layers, some support for the rearmost shelves may also be necessary.

I've included bottom and top shelf STLs — they're not strictly necessary, but they make a more compact unit.

I've also included STLs for some bracing pillars for the back shelves, in heights to fit one, two or three levels. If a higher brace is required, two of the shorter ones can be glued together.

Edit 2023-05-05:

I've now added a pair of stepped brackets that tip the whole shelf assembly forward by about 20 degrees, reducing the depth of the whole thing and making it more compact.

The bottles are still held securely in their collars and by the lipped shelf beneath.

And Lo!

It works very well. There are a few hours of printing there (about twenty for this many shelves) but then it's not as if 3d printing is a labour-intensive affair.

I'll probably replace that hardboard one to the left of it at some stage, partly for consistency, but mainly because with my 3d printed version I can get an extra 50% paint storage space for the same footprint.
