The file 'Wavy Sponge Holder 3D Printer Model' is (stl) file type, size is 12.8KB.
I wanted a sponge holder that would air out the underside and have plenty of drainage. I printed this with no supports and in an up rite position. Just peel it off of the platform and put into use. Scale to fit your space and sponge.
