Hyper Series Rocky Rocketship I have been getting dialled in with some of Creality's Hyper Series PLA today and I may be biased but the Little Rocky is a perfect calibration tool to test for stringing, heat, speed, overhangs and bed adhesion. I designed Little Rocky to do exactly that on the K1 and other high speed printers. This one has been printed in Hyper Series Black PLA on my K1 Max at 220mm/s with 20% infill and I think it turned out really nicely for a 40 minute print. This calibration tool would taken well over 1hr30m on a conventional non Klipper printer. The Hyper Series clearly helps to get the most from the K1 and K1 Max.
