Mendel X-axis drive pulley with a round hole and 3 screws to hold it
by Kulitorum, published
Description
I drilled the holes up to 2.9mm and put 3 M3 screws in there.
That really made the pulley stick, without destroying the motor shaft.
Turned out my problem was with my power supply, not the pulley begin loose.

There seems to be an Euler issue with one of the teardrop holes. Any chance of a tidy-up or the source, or even just inverting it so I don;t have to load it into AoI ? :)
Erik, it would also be nice if you could provide a template (an possibly additional features) for your script to produce a pulley identical to this one that Kulitorum has designed.
Could you make a version for the y and z axis please? :D
Or would this work for them too?
This will be useful and save me from filing down the stepper motors!
Thanks

Instructions
Press the pulley onto the shaft, and fasten it securely with the 3 screws.
You may have to mount it while the motor is mounted on the reprap mendel - I did. Also, the thick part faces down, not up as it intuitively would.

Thanks! This is very good, I did print it and looks to work well. I just don't have tested it yeat because I don't have with me the belts nor the Mendel assembled.
Does it works also for Y and Z axis?
Nice. It would be useful to know for which belt it is, exactly... (pitch, width, notch depth)
In case you need slightly different parameters (e.g. different belt, different diameter), you can use my OpenSCAD timing pulley script:

It allows you to affix it to a threaded rod with nuts, and a set screw like this one (its diameter can be configured). Any belt can be supported.
