Printed quick, clips on tight, but isn't too hard to put on. Tubing fits well. Great design. Worked just fine in PLA.
Thanks for taking the time to design this. I tried 3 others before finding yours. None of them would fit correctly.
One question. How long should the tube be that's coming out of the top be to help prevent the spool from hopping when it gets low?
These are the simplest caps out there that do the job and don't fall off. The others fall off eventually because they cover the button part with a cap (and usually a stupid logo) which loosens up as the feeder moves forward and back with the button. Sorry it won't let me give you a rating for some reason but I would give you 5 stars if I could!
