THIS THING IS SO USEFUL!!!!! I actually din’t know that the K2 plus ‘deposits’ little cones of filament through a chute. When i found out, After vacuuming the carpet multiple times to DESTROY a remnants of filament left in my carpet, i immediately search Creality cloud for designs. I found ones that you had to unscrew every time to dump the cones, ones that sat on the ground, but i wanted something different. And voilà. There it was. This design! I instantly downloaded, print, and attached it to my printer! Works like a charm! I absolutely love this thing. Super helpful! 10/10 design, and have already boosted, and will be boosted again!
