This print justifies the 3d printer in my dear wifes eyes:

It was the very first functional print I designed. By now this is probably the 10th version and I feel comfortable enough with the design to share it.

Function

• Holds together a spool of thread and the mini-spool you need for most sewing machines.
• Snaps together so you can create beautiful rainbows of thread! Yay!

Printing

• Use standard profiles.
• No supports needed.
• Works best with PETG (because it is less brittle).
• One spool holder prints in roughly 20min on my Original Prusa i3 MK3S.
• Print many at the same time!
