Holds shaving soap block and cups the crema whilst lathering up the brush. Also renders soap useless for anything else, thus protecting it from the ravening spawn who would misappropriate it. The soap I used is from Mermaid Bay, is un-perfumed, hard and lasts for ever, and made by them (not some cheap industrial soap base gunk). www.mermaidbay.co.nz .This fits a conical frustum shaped block of shaving soap. Soap is retained underneath by a ring press fitting over bumps. Printed at 0.35mm. Fully parametric, and customizer compatible. $fn= parameter can be adjusted to improve smoothness. It has been commented out as the customiser doesn't like it. So for best resolution probably generate STLs at home. I have been having a problem with openscad crashing during stl export with higher $fn= numbers, hence the blind areas are at lower resolution
