HP97 Desktop Calculator Printer Idler Gear

thingiverse

This is an idler gear for the HP97 printer. I used PETG. It's a bit crude but it seems to work for my machine. I installed it hub first because the 3D print had a slight taper to the teeth. If you have access to a 3D printer then you can try this solution before spending more on other ones out there. Good luck.
