Ive been always wondering what to do with empty spools and leftover filament as i do not print much toy stuff, so i created a hardware organiser from the Bambulab spool and 2 printed parts for wich i use leftover filament on spools.
The upper part of the Bambu spool is the lid using the spool lock mechanism.
Print 2x Bambuniser tray, filament does not matter.
When inserting the first tray please seat the first Bambuniser tray on the little “extruder block”. see pictures.
The second tray you just seat on the first.
