UPDATE late Sep 2025: Added a spool sized for eSUN spools.
I also added a spot for a pop-in label (didn't like the idea of having to write it in). I've included a few STL label files with multiple bodies so you can “split to parts” and change the colors or just use them as negatives. The labels pop in to the space in the short side.
I was having AMS 2 Pro issues with Polymaker cardboard spools. I tried the electrical tape trick which was better, but still gave me issues. Plastic spool covers didn't work for me, nor did the various adapters, I just wanted things in one piece without fiddling with multiple parts.
This was by far the best printable spool I found, but it did not have any sizes that would fit the cardboard core of Polymaker spools (even the fusion 360 parameters maxed out at 80mm while polymaker core's ID is 89mm).
I added some spacers so it would fit after ripping the cardboard sides off as well as a notch to fit in the Polymaker's notch to lock it in place. Works great in the AMS 2 Pro now! I printed in ASA, 0.4n, 5 top & bottom layers, 4 perimeters
