This holder is my first design. Nothing fancy just a simple holder for two mini mills produced by WMF: https://www.wmf.com/de/en/mini-mill-3201000811.html

Also this model will let the place clean where this mills located.

The print does not need any support or brim and print fast. I printed them with 20% infill to increase the weight a little bit, but that should not be necessary.
