With the announcement of HT hotend I'm trying to insulate as much as possible my CORE Ones so I designed a plug for the right panel hole.

I kinda liked the Biomec's one (here) but I wanted a rubbery seal like those in silicon used to protect the cables through the panels.

So I designed one in TPU that is press fitted in place. 

I used 90A TPU, any similar hardness or softer should do!
