I just unboxed my CR-6 SE and it works fine, however i would like to use the space left of the printer for something else than the filament.
So i just designed this spoolholder for the top left corner of the frame.

It fits really well i think, now I will check if the filament is properly fed from above.

I will also cut a M5 threat into the hole of the extrusion-profile to secure the holder further.
Might also release the inventor file for anyone who wants to adjust on their own.
