I printed this yesterday for my shower drain. I could not find anything on the market with a hole in the center. The squares need some tweaking, but it works for my purpose now. Plus, it took less than 10 minutes to 3D print at the public library. http://www.thingiverse.com/thing:815585
@Mark_Rehorst Thank you! Yes, a few of those dividers are too thin. I designed it myself and i printed it in the maker lab at Chicago Public Library downtown.
Looking good! I haven’t seen any prints from libraries.
As for the design, maybe design by adding together thin dividers instead of cutting holes.
Keep up the great work!
