HP C8543X toner cartridge drum adapter

Have you ever wanted a tool to help turn the photosensitive drum to clean off smudging toner? It was very hard turning the drum on my C8543X cartridge for the HP 9050 printer in the office. So I looked at the turning mechanism and modeled this part. The mating geometry was a very interesting triangular shape that was rotated like a screw thread. I only uploaded the triangular mating part and to use this it can be joined with a suitable handle. For my print, it was joined with the Ender 3 Extruder knob.

I printed in PLA with 40% infill and 3 walls.
