HP 91/92/97/97s printer spur (idler) gear

[Geoff Quickfall]

Firstly, thanks Katie for the following as I did use this repair on my first 97:

Now in know there have been replacements but i am obviously not doing the correct search as I cannot find the recent posts. However, the waiting period has been over a year so here are the specs, thanks Katie! (Reproduced from Katie's article):

- 80 pitch - measured by the pitch diameter method (not the circumferential pitch method)
- 30 teeth
- 1/10" gear face
- 1/4" hub diameter
- 5/64" hub projection
- 3/32" bore
- made of Delrin or nylon

The reason for the post and Katie's specs is that I am too lazy to measure myself, her article has helped me fix four printers but there are no sources for the fear including DAVEHAL2001 who used to sell on EBay.

As a result, I am thinking of a Shapeways product (I need four) available for all to order. I am a newbie and would need help setting up the print with the above specs.
