Use half a shaft coupler as a hub for attaching a 3D printed part to a shaft. https://hackaday.com/2019/09/02/misuse-this-part-to-attach-3d-printed-stuff-to-a-shaft/

I believe the Thingiverse website allows you to configure openscad designs from the website, then download the.stl. But you can also download the Openscad file. .stl is what your slicer (CAM for 3d printers) wants. For a reliable motor-mounted pulley, I ended up doing something similar to what Chris Albertson describes. Mine was a plastic pulley with a hub that has two pockets for clamp nuts. The OD of this hub fits snugly into a metal ring with a pair of radial holes. The set screws run through these holes, thread into the nuts, then bite into the motor shaft. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
