Sponge holder

Print the body first, then one of the legs if you need them. Check if it tightly fits into the body and if the length is fitting the dimensions of your kitchen sink or whatever else you want to put this on.  If not adjust slightly in your slicer by stretching just one needed dimension at the time. Then print two legs.

I made them to fit fine but there can be some tolerance differences due to your specific printer and setup. If that happens, its easy to solve as described above.

You only need minimal supports to do the "leg" holders on the sides.
