I printed a small sponge holder a while back and have been using it about a year now. Ive been seeing these ads for silicone drainers lately and decided to make something similar. This is actually v2. The first one had a separate base and grates on top but I didn’t like how it turned out. This is a combined grate and base. Printed in 4 pieces and welded together.
Zooming into the image, by “all one piece,” they mean the grates and bottom plate, as there are seams along the back wall at about one average bed width apart
