Summary

A slightly altered Extruder Drive Block for the Ormerod 3D printer.

After hearing of people experiencing their supplied extruder block beginning to wear through I remodelled the feed from a 50mm diameter to a 75mm diameter.

Hopefully slightly reducing the pressure against the top of the feed channel.

I also extended the support clip a bit where it clips over the X axis. I had experience of the original coming unclipped.
