A shaving stand I created for my shaving set of shaver and brush.
The diameter of the hole for the shaver is 20mm and the diameter of the hole for the brush is 28mm which fits perfect for my Eberbart brush and my Gillette Fusion Shaver.
Use "Adaptive Layers" and "Tree Support" in Cura for optimal results. I had chosen brim, because in the past i had some problems that the tree support is not really bonding to the ultrabase. Could be an Issue of the OWL PLA, idk.
