What is it? Why it's a brush holder. I had an older one I made from wood, but I always found it a bit... lacking. Oh it worked just fine, but it only held a few brushes and it was kind of a kludge, all things being equal.
So, off the Sketchup and Blender I went. It took a while to knock the design up the way I wanted it, but in the end, it came out just the way I wanted it.
What does it do? It holds brushes when I am painting. I have never been good at holding brushes in my hand for 2 and 3 brush blends, so this helps out there quite a bit. It also holds the brushes horizontally while they dry. While storing them in a cup is completely viable, I have heard from really good painters that storing them horizontally helps keep the water from building up in the ferule and causing premature rot and other bad things.
I designed the ends with holes for nails or small screws, but I ended up gluing them to my base after all was said and done. I also used offsets on each end so that you can 'stack' 2 or more of them to create even bigger holders. I actually printed 4 of them so I could make a double stack. I may make another for some other brushes I have around as well :) Here is the whole thing in pictures;
And painted metallic blue. I should have used red so it would go faster.
