A simple brush holder compatible with Ikea Skadis. It is composed of an upper and a lower part, that together keep brushes separated and organized. No supports needed.
Be mindful when pushing the pegs into the holes of the Skadis board, as the smaller part might break if your printer accuracy isn't very precise.
The author remixed this model.
I reused the pegs from this model, as they were a perfect fit, and attached to the rest, which I've modeled myself.
