Gears for Servos and Steppers Answered

Hey guys (and gals),

I've been researching this a lot, but I still haven't the solution.  When you are working on a project and you need a gear for your stepper or servo, where do you acquire it?  For example I work a lot with TowerPro 996 servos, but I haven't found any third parties selling gears for them.  

Same thing for motors.  If you are using a stepper motor, like a NEMA or something where do you find a gear that attaches to it?

I've seen gear kits on ebay for sale at under $20, there's shafts and a means to build them into a gearbox. You get about 30 diff. nylon gears.

I have been in the same boat...
Finding a stepper motor is easy, finding a suitable gearbox with the ratio you need often mean "Mission Impossible".
So far I ordered them all online as a complete pack, motor with gearbox already mounted.
For some projects I printed the gears but in terms of size and long term reliability that is not be best option.

Thanks for the reply. Yeah, I recently bought a 40w laser cutter, and I could cut my own gears out of wood or plastic, but I still wouldn't know how to securely fasten them to a motor or servo.

Check the various models of the "Wades Extruder" on Thingiverse!
The printed gears for the servo have a hole and slot.
Put a 3mm nut in the slot and use a 3mm set screw to fasten them in place - works a treat for me.
And with a laser cutter it should be no problem to do this.
Although a drill works too for the holes, just the slot might be easier to burn away.
