I used the "hanging kitten" outline to design a sponge holder for the kitchen
Prints easy without supports. I used PETG, but PLA will also work fine.
The tray features a drain to the front to let the sponge completely dry.
Width for sponge is 45mm, fits fine for kitchen sponges with green abrasive side
I included the Solidworks and step Files also for further remixing - have fun!
