Simple kitchen sponge and brush holder: Designed to hold a sponge of 100mm x 80mm or smaller. The brush holder is 21mm x 21mm. And conveniently rounded on one side so the brush will always face to that side. I have include a lefty version as well. Went though model repair service to ensure a mesh correct STL output. :)Designed by myself in 123D Design. I have included the source file for your pleasure. :)
