Scrub Daddy / Sponge Kitchen Sink Drainer Holder

Designed this scrub-daddy holder to rest on the metal wire drainer of my kitchen sink.
Can also be used to hold other scrubbers/sponges of a similar size.

The design features:

• Rounded design to suit a normal scrub daddy, with a fair bit of tolerance to allow a loose fit.

• Large drain hole at the bottom.

• Side holes to allow air through to the sponge.

• Hook intended to fit around a 4-5.5mm bar.

  • 10mm gap between hook parts.

This design requires something to rest against to not just flop down and spin on the hook. See second image where it rests against the metal bar of my drainer. 

I've designed it to be printed without any supports needed, with it printed up-side-down. Will result in some overhangs towards the drain-hole as it gets toward the top of the print, but should be a doable overhang with most printers.
