Climbing brush - Disposable head - Custom handle

I wanted to create a high cuality brush. Something really usable wich is not thrown away after worn out.With this model you can have a cutomized climbing brush and you only need to reprint the brush head once it is gone. I must say it was not easy to optimize de desing and the printing profile for the bristles. The first prototypes had thicker bristles and the performing was just OK. After comparing it with comercial brushes, I could realize about the importance of achieving the thinest bristles with the higest density.I belive this is the best printable bristles with a 0.4mm nozzle. I recommend to print the bursh head with PETG in order to get the best performance and lifetime. It also works for PLA, but problably you will need to replace the head more often.The printing profile for the brush head might be slow, but keep it if to assure the best quality. I'm looking forward to read your opinions and printing experience with the model.
