STL to Waterproofing a motor 6384

Hi,
i want to waterproof my 6384 with thermal conductive epoxy or with a thermal conductive silicone glue. I would prefer to pour it. I saw someone on insta using a 3d printed sleave for the spool/windings.

i think it was @kkolli - would you be willing to share the STL - or does somebody else has something similar? It would be highly appreciated! THANKS
