I had some other stuff to order from SMW-3D so I got my flexible couplers from there.


On a different topic. If you want a direct drive extruder drive gear… don’t cheap out and buy something from an Aliexpress seller. The one I got has practically no grip on my fillament and now I’m looking for somewhere I can buy a good quality one.

Not mine, don’t know the seller etc etc:

I’m about to start building. I’ve bought a set of printed parts to get me started, with the language barrier I didn’t manage to get X ends with support for the lead screw stepper motors I want to use.

Has anyone else printed X ends for lead screw steppers? Can you point me to appropriate stl files, there seems to be a few out there.
