Will this work? The stl is generated from the parameterized mendel project (openscad).
I'm sorry I had to zip it, but it was just a tad larger than the upload limit unfortunately.

You're welcome, and yes I'd agree it "feels" different, but they do seem to have the same number of teeth so should be good.

From the openscad file:
//spurs
for(i=[1:20]) rotate([0,0,i*(360/20)])
translate([15,0,11])spur();

For the regular pulleys I had to make the teeth larger to get a good print, but that may be my printer settings. And I haven't tried to print this z pulley.
