Grommet for 1" Hole

thingiverse

I wanted a grommet for a 1-inch hole that required only a few wires to pass through it. I drilled holes for zip ties, just in case, to provide extra strain relief. This design is based on this original model: http://www.thingiverse.com/thing:4880 CAUTION: Modifying a power supply as shown in the images would void any warranty and isn't UL certified.
