HP Plotter Cutter Gear
thingiverse
Replacement gear for the cutter assembly in an HP T120 plotter (probably also used in other HP models such as T520 T525 T730 T830). Might be HP part CQ890-67091 CQ890-67108. This gear broke and given that there are sellers on eBay making copper replacements, I have a feeling it's a known issue. Save yourself a few bucks and print your own!
