This is a separation roller holder for Kyocera machines. It's a part in the paper feeding mechanism that takes up paper from the storage trays. Printed in Spectrum PLA on a X1C and tested on a TASKalfa 3050ci, works perfectly fine.
Printing orientation in the 3mf is important. You need to snap the original rubber roller into the part and different orientations tend to snap apart during this process.
