The design is very good, however I had very hard time printing it from ABS on my P1S. I’ve bought some very cheap ABS (rookie mistake) I had a lots of cracking and warping. After a lot of tinkering, setting, calibration it came out reasonably good. Printing this model taught me a ton about 3D printing, transferring this knowledge to easier materials highly upgraded my print quality. Thank you for your work!

Fits perfectly to Alzament spools.
