The spool's width, diameter and spindle size can be customized but its main feature is it prints as a single part without needing any support.


  • Added a selection for a smaller spindle.
  • Displays estimates for how much the spool can hold by weight and length.
  • Performs some basic checks to make sure the spool designed can be printed.
  • Does a better job at limiting the diagonal walls to a maximum of 45 degrees.


The side walls of the spool and the spindle are at a maximum of about 45 degrees so it should print easily without any support as a single piece.

I printed the default settings for the spool with 4 walls (or shells) and 20% infill. The default spool settings will hold about a 1/2 kg of filament.

Note: If you still have trouble printing unsupported with the hollow, or shape-removed options, try the non-hollow or non-shape removed options.

I see you're using Taulman 618 that's died. I love 618!

Would be even better if you could reduce the spindle to much smaller. I like to have my spools hanging on a 6.5mm metal rod and would rather have that for the spindle rather than try to create inserts.

I just added the ability to select a smaller spindle and a few other changes. Hopefully I've tracked down most of the bugs. Give it a try.

Thanks, I'll start one tonight!

Thanks. Thats been bothering me too. I'll see if I can build in a smaller spindle.

Thanks, much appreciated!
