Simply a brush holder. You can use any material, I printed from the rest of the filament.
With a 0.28 layer, it is also relatively fast printing.
Supports are not necessary, but you can use them if you want.

Jednoduchy holder na štětce. Muzes pouzit jakykoliv material, ja tiskl ze zbytku filamentu.
Pri 0,28 vrstve se jedna i o relativne rychly tisk.
Podpery nejsou potreba, ale pokud chces, muzes je pouzit.
