I needed some temporary holders to get paintbrushes and sculpting tools out of the way on my workbenches. These will do until such time as I decide whether or not to design more specialized holders. Will add taller sizes as I need them.

Inspired by Nishihara's Gridfinity Single Brush Set Holder.

NOTE: Make sure your Hole Horizontal Expansion and Print Thin Walls (Cura) or similar settings are properly calibrated/enabled.

Obligatory link to Zack Freedman, who has made it possible for me to finally start organizing my workbenches with his Gridfinity system. Thanks, Zack!
