I wanted a grommet for my dry box to allow the filament to get from the inside to the outside, using but without having to drill little holes for screws etc. So came up with this thing.
The only hole required is a 20mm hole, which is later filled with this grommet.
The hole is designed to allow a 4mm OD PTFE tube through (you may need to help it with a 4mm drill bit). and the inside is chamfered to allow the PTFE tube a controlled bend towards the appropriate reel of filament.
If you prefer to use a wider PTFE Tube, the hole can be enlarged with a drill bit out to 6mm if you wish.
The screw thread is nice and chunky so its easy to fit, and tighten sufficiently, You could always run a thin line of sealant around the grommet head the offer a near perfect seal.
