When I acquired the Elegoo Centuri Carbon I loved being able to have a coil inside the printer itself and that the humidity (very high where I live) did not affect it as much due to the heat inside. I found similar models but the coils didn't fit properly, so I made this design adapting the outside one to be able to put it inside.

I printed it in ABS, because I use that material a lot, but I suppose that simply PETG will work well.
