This is a simple paint rack that can host up to 9 Vallejo dropper bottles (17mL).
I designed it so that it takes the least amount of space possible while still ensuring the bottles will not fall out of it easily.
The holes fit closely to the bottles but not so much that it is hard to take them out or put them back in.
The size of the model is 23cm x 2.55 cm and it is easy to align them if you print multiple.
I printed with 50% infill for some strength but any setting will do, and same for the rest, it is not a challenging print.
