A simple 3-piece stand to store paint brushes that I bought from Amazon. The plates are printed separately and screwed to the base part with threads.
Print the thread sections with 0.12 mm layer, for the base model 5 walls may be required for strength.
Threads are initially hard to screw but with a little bit of force it can be done.

The author remixed this model.
In the original model brushes were keen on falling due to being a different brand. So, I inspired from the original and created a brush specific model.
