HP 46/81 idler gear

[Duane Hess]

Was at the local library and they have the Innovations Studio in town. Laser cutter, CNC router, 3D printer, etc. Its somewhat "canned" so making your own custom stuff has difficulties. At least with the utilities they provide.

Never saw a 3D printer in action and was surprised with how fine a "thread" it can extrude.

Which made me wonder, with all the expertise here or elsewhere has anyone tried to 3D print the idler gear for the 46/81 printers? (you know the gear that always breaks) When its done some whittling or filing might be necessary, but "cleanup" for the produced item seemed easy. (they were making a cookie cutter)

Over my head. Anyone have thoughts on that?
