Anycubic i3 Mega Spool Holder

After starting out by making some spool hubs for the rolls of filament that came with the printer, which worked very well, it soon became apparent when I bought some more filament and the spool was a different size centre that I would have to make lots of different hubs which would take forever and use lots of filament.

I decided then that the best option was to make some rollers for the spool to sit on and make them adaptable to different spools. After various trials and not being able to find what I wanted elsewhere I made my own which conveniently fit on the Anycubic spool holder frame.
