Original size didnt fit this spool (did fit one anycubic), but adding 1mm to total diameter did work the magic. Really useful!!

Printed the regular size, but that didn't fit in the AMS. Printed the thinner version and it seemed to work fine, however it still feels quite loose on some polyterra spools.
Would likely print the smaller version if I hadn't printed several pairs already

Perfect. Exactly what I needed. Thank you.

Thinner version worked better for me!

perfect fit on damaged plastic Kingroon spool (edited)

Fits perfectly on my spools. One I've not seen mentioned is justmaker.

Fits great on my Elegoo spools. Sadly, it prevents the Creality CFS from closing. I'll have to look to see if I can do a mod to the CFS to get it to work. Maybe it'll just be a latch adapter.

Works well, fits Polymaker, Elegoo, and 3DHOJOR spools very well.

Being that this includes the actual .f3d file to allow you to tune the model is what sets this apart from all of the others out there, imho.

I used ABS for mine (only because I was too lazy to swap out spools) and realized that I needed to increase the diameter by about 1mm to adjust for shrinkage. Been good ever since.
