Upgraded from a NEMA24 to a NEMA34.
Before going out and milling or buying it in metal it is always a good idea to testprint it.
Probably will use the plastic part for a while as 3mm wall-thickness PETG seems might already be good enough.

For us beginners in 3d printing.
What do the numbers in nema moters actually mean.
I recognise they go up in size/power. But being from the UK. And Nema being a US standard. I'd love a guide.
The number is the width/height of the mounting face in inches. So Nena 17 is 1.7inx1.7in on the mounting face, nema 23 is 2.3inx2.3in etc. though looking at datasheet for different nema sized mount that seems like an approximate not dead on number.
Shaft diameter and length is also part of it.
NEMA is just a mechanical aspect and contains zero information about the performance. Equally comparing motors by torque isn't the full picture as the inductance (and other aspects) can be different. Equally important is the stepper-driver & supply voltage.
Yeah and as its mm when sold here. Unsurprising why I could not see it.
Thanks for the help.
