These are new variations of the "Brush Caddy" already published.(https://www.thingiverse.com/thing:5794271). The general design is more compact and prints nicely with a minimum of support. I've included four different files that differ only in how wide the "throat" is. A 2mm difference between the several models will help zero-in on the brush size.
