Modification of Synthetic Electron “internal spool holder v3” adapted for enabling spool quick change (similar to the “Quick change” remix performed by TB for Synthetic Electron “internal spool holder v2”). Can handle spools up to 68-69mm.

Beware, you'll need to have sufficient internal space to put it in, and choose a filament that resist to temperature as this piece is intended to stay inside of the printer (PLA is not suitable).

For further instructions on how to install & how to use it, refer to the original post by Synthetic Electron, where all details is priovided, and videos are availlable.

Don't forget to thank the two original authors @Syn3D_3309286 & @TraeBaham_3512959 for their creations and for enabling remixes

If you need another spool dimension, just ask me and I'll add it to the 3mf file

Info update 12/2025: I have it running for a few months now without any issue. I was initially afraid about what would happen when I need to change spool in the middle of a print... or if there would be some issues replacing the spool depending of the height position of the plate... But I never had any issue so far
