Printed well. Fits bambu spool perfectly. Just what I was needing to refresh my wisedry desiccant packets in my sunlu filament dryer. Printed in PLA at first but it warped a bit at 60C in the dryer so I reprinted in PETG using Bambu defaults without any calibration. I could tweak settings for a more finished product but, as usual, Bambu's default settings usually get you really close to where you want to be.
