Bambulab A1 & A1 mini fast spool holder extension

update V2: 

in early 2025 bambulab modified the A1 mini spool holder . the size of the outer part has changed. originally it was about 31mm. the new version is about 31.5mm (i made 2 specific files for the new spool holder - called V2).

 

 

Spool holder extension for bambulab A1 and A1 mini printer.

 

Print in 18 minutes with less than 10 grams of filament.

 

Accessory to be used with the roll holder supplied with the printer. 
It fits into the external part and allows you to use wider reels (usually cardboard reels).

I made 2 measurements: one extends for rolls up to 80mm wide and the second allows you to use rolls up to 100mm.
