You can never go thicker layer or narrower line width than the diameter of the
nozzle. Somewhere over 100% to 150% width is where you want the width. Under
50% of the thickness makes it harder to extrude.

Looking at that *.3mf file I can see the cause of the problem,There are
39 non-default settings but the big problem is near the top. See the

The "line width" is set to 0.3 and there is a 0.4 nozzle on the printer.

I'm getting the impression that Cura is a project :-) I know you don't want to
spend your time looking at videos, this guy has 20+ short videos
This is why posting a screen shot or 3MF is needed. The 0.3 could be
anything. When I make something I keep the .STL, the .gcode and
the .3mf files together in one place "forever" so that if I want to re-make
the part I just load the 3mf file and all the settings are restored.

DO I read this as using 0.3mm line width? If the nozzle has a 0.4mm hole
you must set the line width to 0.4.
Cura will run the extruders at a rate that pumps plastic to make a
linewitdth x layerthickness x speed. So if you say 0.3 line, then it will
pump out 3/4 as much plastic as required

Something is fundamentally wrong.The error in the print swamps the 3mm
pitch teeth. The print as errors that are literally 10x greater than they
should be. Your printer should be making parts with less than 0.2 or 0.1
mm (0.010 to 0.005 inch) deviation from the design.

Maybe just naivete here, but I was thinking about a sacrificial raft as the
base. If you are building teeth in layers from there, surely they would be
self supporting as long as they did not have to support the upper flange? You
don't need an upper flange if that will ultimately be another
Not, stupid idea.I think I will try making a PLA belt. If nothing
else it will be used to verify belt size before ordering. and I will post
the test on Youtube. Failures make for good video.
But it could work, I have a spool of medium-soft TPU. The problem is it
stretches.

Attached is a picture of a 41T GT2 2mm pulley with a 54mm shaft
If you have a SLA printer you can do this if it uses top down
projection. You can stop during the photopolymer print process and add
components for support as long as they don't shadow any layer above.
