The 120:1 Mini Plastic Gearmotor 90-Degree 2mm Spline Output (https://www.pololu.com/catalog/product/1123) motor is just about perfect for my application. It would be ever so slightly more perfect if the drive shaft extended out both sides of the motor (not just one side).
Is it feasible to replace the drive shaft with a longer one, so that it extends out both sides? (Assume I have access to an arbor press.) If so, can someone tell me a source (and perhaps part number) for the same 2mm spline shafts that Pololu uses?
Thanks in advance.
