On my EQ3-2 mount I wanted to mess around with the shape of the DEC clutch lever a little to give more clearance for hardware on the mount. I don’t want to damage the supplied (metal) lever however, so I removed it and redesigned something as close as I could get in OpenSCAD. It’s not a perfect copy, but this should allow me to experiment to see if what I want is even possible.
The hole in the centre didn’t come out quite as neatly as I’d have liked because the taper was unsupported underneath, but that will all be covered up by a screw so I shan’t fuss about it too much.
