Hi. I need a few simple low-precision gears. I intend to ask my waterjet guy to do them.
But, I don't do CAD/CAM, and he likely does not speak gear or have gear software.
Does anyone know where to find a downloadable model or file with which he can cut a 3 mm thick, 54 tooth spur gear in either Module 1.25 or 20DP with a 20 degree PA?

Or would any of you kind gearhead souls be able to provide one?

Said gear would also have a 19 mm center hole, and four equidistant 3 mm holes at a radius of 15 mm from center.

Anyone?
 
Indeed, even my OCD had to dodge this one. Truth is, the gears just don't fit in my very small hobber. And even if they did, there is a time crunch to deal with. Low demands on the part... So, waterjet it is.
Thanks a bunch.
