I needed a cable grommet for my Ikea Platsa closet, where I have my printer, and all the other grommets I could find where either impossible to get to fit right or too large.
So I made my own.
It is made with a 30mm inside hole diameter, and requires a 38mm hole for it to fit into. The lid has a gap for a 8mm thick cable.
I've also included a tool for tightening them easier.
The lid is designed with snap-in connections, so it might seem tight, but that is to prevent it from accidentally coming loose over time.
Print suggestions
The model is made with tight clearances when printed with a .4mm nozzle and .2mm layer height.
The author marked this model as their own original creation.
