Hard Hats for the Door Hinge Screw Caps - K1/K1Max glass door screw cap by [%6560541617] I had some grey PETG filament to use up and this clever little design was perfect. Really easy to print and does what it says on the tin. Print, pop into the USB slot and job done, Simplz. Printed as part of the November Print Event https://www.crealitycloud.com/contest/november-3d-printing-event. Printed on my K1 Max in grey Eryone PETG filament (overkill I know), sliced on Creality Print with 100% infill, no supports and at 90mm/s. I had to print slower as I was using PETG. They fit perfectly, not overly tight making them easy to remove if you need to and great if you want to pimp up the look for your printer. I might go down the Orange route and print them again.
