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.
I think he was talking about the grain of the print. The grain is perpendicular to the flow of water which would allow water to stay between the gaps.
I guess so. The large horizontal lines are “steps” from the layer lines. I printed at 0.20mm. It’s never going to drain every little bit of water. It just needs to not pool water.
