Does anyone know a good place to pick up a Nema 17/23 0.4Nm or greater? Or does someone have one for sale?

Maker bot seems to be sold out, and Sparkfun's steppers look to be too weak.

We seem to be finished our build minus the extruder stepper being too weak, so we need one stepper to finish the build sad smiley

I got mine from ausxmods.com.au, not sure whether you want to pay the postage to wherever you're located though.

If you remember f=ma, you can calculate torque figures in kg.cm and oz.in which may aid in your search. 0.44Nm is about 62 oz.in or 4.5kg.cm.

Umm I am in Canada, which I should have probably posted originally (postage from au might hurt a little lol).

Thanks for the response though.

I've got some 5 kg*cm Nema 17 steppers from Kysan in Vancouver, but they have flats on the shafts; they won't work for a knurled extruder. I'm looking for a really small gear to mount on them, but haven't found one small enough yet.

Alltronics sells stepper motors for only $9 if you're in the u.s.
