I wanted a holder for my dish brush that sit next to my Pluring dish cloth holder. The holder has approximately the same size and look as the Pluring. I just made sure it worked for the type of dish brushes I use (ICA's own brand in Sweden).

Printed it with the 0.20 mm structural option in Prusa Slicer. However, it will probably print fine with almost any settings.

Update: Added an insert to make it blend in better next to the Pluring. Not really a press fit, I needed some superglue to make it stick.
