Desk Cable Grommet

I printed two grommets to cover holes in my old workbench. It was a simple design and only took 20mins print on my K1C.I just thought I'd share a few sizes for anyone to try out.No caps or lids - Just the grommets.I added the following diameters:35mm, 50mm, 55mm, 58mm, 60mmThey all have a depth of 35mmPrint it upside down to avoid the need for supports.
