18mm Split Grommet

I created a couple grommets a while ago for lightboxes and other things I print. I seem to find myself putting a slice into the grommets 8 / 10 times I use them so created a version with a slice which makes it easy to compress, put in a 18mm hole (or 18.2mm hole) and it expands back out. I print them in TPU.

This can be used in lightboxes you sell, includes commerical license.
