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 don’t think it will break anytime soon.
Regardless, E3D toolchangers weigh about 30kg (the equivalent of approx. four Ender 3 [by weight]). If it broke, the printer wouldn’t move much, but there would still be a big mess as the spool would fall to the floor and unroll.
