I designed this to fit in the corner shelf of my shower. I built it from the ground up but used piuLAB's soap holder as an inspiration.I printed the main body using 0.4 mm layers so it printed under 2 hrs. The grate I skipped the top and bottom layers and used a hexagon infill. You use any infill to get different grating patterns. The other option would be to take the raw grate and add holes to it via a CAD program.
