Which MFG has the best spool and have you printed a spool?

I’ve been evaluating over the last few months better spool options when I am respooling filaments. My results have been a very mixed bag indeed. I even went so far as to design my own spool but that too was mixed results.

So please share your printables or thingiverse spool links but please don’t turn this thread into a popularity or self-plugging fest. If you have had good luck with a spool, please provide the link and answer these questions so the group can benefit from your experience. I’ll add mine later in the thread so as not to influence the early discussion too much.

  1. Link to the printable spool.
  2. Why do you feel this spool was superior and what are you comparing it too?
  3. How long did it take to print?
  4. How much filament did it take to print?
  5. What do you like best about the spool?
  6. What do you like least about the spool?
  7. What commercial filament maker do you believe has the best spool and why?
  8. What printer do you have and do you use an AMS?

Based on the trajectory of the discussion, I may add a poll to the topic.
