Needed as soon as possible a spool holder for larger spools so printing anything that is dozens of hours was out of the question.
Solution? Looked at the heavy shelves and had an idea.
One remix later, a 1-hour print and with some round wood that was lying around this spool holder was born.
I like the position of the spool so much that it is here to stay.
I had only a 3kg spool of filament, so I just rewound filament onto smaller spool by hands.
