This is a sponge Holder I designed for my new place to make sure the sponge isn't lying in the sink and gets lost in dirty dishes. Also it has plenty of holes for the sponge to drip and dry so it doesn't acquire that musty smell as fast.

This holder should fit sinks that are separated by a divider that is approximately 3.6cm in thickness. The mount is designed so it has some bend to it, so it can fit a sink divider smaller or bigger by about 5 mm. I can adjust the width of the mount depending on the interest from the people, so if you want a bigger or smaller sizes I can quickly adjust and post more step files.

I suggest to print this on the side so the mount is strongest and can have some flexibility.
You can print it at 0.2mm and 15% infill, it is plenty strong.

Whichever way you decide to print, you will need supports, either to support drain slits, or to support the mount.
