A spool holder for the flux delta 3D printer. Does so the spool can sit on top of the printer in a vertical position. can hold 500g aswell as 1kg spools, which I have tested without problem. It can perhaps hold even bigger spools, depending on the diameter of the spool.
NOTE: the tube has to be changed to 205mm in height and 34mm in diameter if the measurements aren't like that when you open it.
infill: 15 for the holders, 20 for the tube
