1Kg Spool Adapter
thingiverse
1Kg filament spool adapter to fit a 20mm printer spindle. I noted that my spools of PLA have a much larger diameter center hole than the spindle on my Anet ET4+ printer, and it didn't turn evenly when printing. As I didn't want the filament to break, I designed this adapter. Print at whatever resolution you like, as it doesn't have to be pretty, just functional. I used a standard .4mm nozzle. Total height is 68mm. Spool diameter 54mm. Center hole diameter 20.5mm. Slide the spindle inside the spool and install on your printer's spindle. Add the washer and secure with the spindle nut.
