Low profile quick-swap Spool roller holder; Also for wide rolls of filament 2.5kg

I was annoyed of my current spool holder, as I had to adjust it to fit filament rolls of different widths. With this design I can just put a roll on it and swap them easily.

The design requires:

• 4 M6 Screws
• 4 606ZZ bearings

The bearings snap in place and do not come loose when lifted. You might want to add a washer between the plastic cylinder and the bearing.

The 70mm cylinder is for normal 1kg rolls and the 110mm for 2.5kg.

Printing the cylinder: I print it standing and use a 5mm brim to add some grip to adhere to the printing bed.

Let me know if you want to use a different bearing or need another width.

I am not sure how well the internal threats work on other printers. I printed mine with a 0.4mm layer height and a 0.6mm nozzle. They were ok. Feedback on the design is very welcome! :)
