About this 3D model

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.
