Gridfinity Prusa nozzle brush holder

Simple storage block for Prusa's nozzle cleaner. The brush can be fitted both ways, but I prefer it facing down to keep the wires clean.

Version 1 is a bit tight, and will keep the brush in place when flipped upside down. Version 2 is looser (+0.5mm wide, +1mm long, +10° angle at the bottom), and I'd only use it if you need your brush very regularly.
Update: for some people, the “tight” version is so tight that the brush doesn't fit… A bit of sanding might be required. Use the looser version if not sure.

Based on Stu142's very useful blank model.
