I have saved my old Prusa spools and looking at printing hubs to replace the cardboard and make them usable. Of course, it depends on the cost of spooled vs unspooled filament.

I may have to build an winder to make it work.

There are places that sell filament that is not on rolls, You can build/print a device to put this firmament onto the rolls.

I assembled the V-Spooler for this. Works well. I've respooled all of my HT and off-brand filaments onto empty Prusament spools.

They are great for extension cords, lengths of coax and wire. Christmas tree lights....

Empty spools can also be used for other things around the house. Like when taking down a string of lights or garlands (most commonly right after Christmas, but could be for packing up after other celebrations), you can use the empty spool to wind up the light string or garland for storage. Storing extension cords can be another use, I'm sure there are other long flexible things that could use a storage spool that I'm not thinking of. Not just for your own things, but maybe friends/family would like some of your empty spools for their own reuse.

I've kept the empty spools (3 so far) of the new all plastic NFC variant and have rewound my generic filaments onto them.

I keep a couple of empty spools just in case I need them in future. If I can buy refills rather then a new entire spool, I will. If not then I recycle the empty spools if not required, but I always ensure I keep 2 or 3 'just in case'.

There are some interesting projects on Printables where you can reuse your empty spools to make stuff too : https://www.printables.com/search/models?q=empty+spool

Hello Joan,

Thank you for your reply. Yes, I saw it in the shop, but it was only available in a limited range of colours (white, gray and black).

Best regards,

Gerald

I bought some Prusa Refills, and re used the Prusa plastic reel sides to complete the rolls for the refills
