Brush-Holder for 2 up to 5 heads

I created two versions:
- Version a has a drawer to get the water out of the Brush-Holder. (3 Parts to print)
- Version b must be turned upside down to get the water out. (1 Part to print ...after
testing for a while I would recommend this one.)

Changelog: Improved design, which is guiding the bristles into the hole. (The preview Images don't show the actual design. For an exact preview load the 3d preview of the .stl thumbnails)

If you wish a version for...
