New version (V5) of my chain mount to NEMA stepper motor on Z axis.
When i printed this the orientation on the printingbed is best with the chain side to top and cable hole on the uperside.
The first versions where not strong with 20% infill , now i did use 100% on V5
V5 Fitting is nice and thight on nema.
Take care to fit chain to it and carfull mount to nema do not stress the noches
If the mount do not click on nema because of tolarance, you can remove 1 mm in the centre of the mount , ( its there for small adjustments.)
