There are a lot of shower drain covers out there. Slicing them, many of them would take excessively long to print due to the many many drain holes or wouldn't be a great candidate for TPU. So, I tried my hand at creating one that would print quickly AND also work with TPU. In my experience TPU does not bridge super well, but I've tried to minimize bridging distances, and this prints pretty well. With a .6mm nozzle and 100% infill I can print this in an hour and twenty minutes at default slicer speeds with a direct drive extruder. Designed to fit over a 115mm drain grate.
