I made this model for a grooming salon to hold brushes and Airdryer fittings.

Build individual holders with the option to lock them together so you can print as many as you need, add more over time and also can be printed in small printers.

I use black PLA with %15 infill and the Standart low quality setting from the creality slicer ( To save time, material and because I didn't need it to look super pretty).

If te brushs is too high may not work when by itself but once you lock few together the holder is perfectly stable.
