This is basically the same stuff pop bottles are made of so fairly robust and waterproof, although a bit of a bugger to glue.
I made it in two parts so it could be attached from either side, and the handy thing about FDM 3D printing is that the layers tend to lock together if you get the clearances right.
This is in General Vod btw who is off to be a daily driver in a week or so, so the new grommets will get well tested  I will report back on how they last. |
If you send me the .stl file or what you have then I can print it for you in flexible filament (ninjaflex). I am designing grommets for the aerial and the central locking rubber boots at the moment, since I have issues with both.
I did a quick and dirty CAD in Tinkercad for the aerial last night:
As you can see in the second pic, the ninjaflex is quite flexible.
What are you using to do your CAD?
