About this 3D model

We all know that cleaning your brush is one of the most important things in hobby painting. And yes, I know most of us just bash the brush several times in some water and hop on to the next color, but when in a rush or just not paying attention, sometimes that brush isn't all that clean, and we inevitably contaminate other paint colors by accident. So simple a fix for everyone who still uses a mason jar or any other glass, this brush washboard will fit and hang in the majority of the glasses we hobbyists use. to keep our brushes nice and clean quickly.
