Ground Screw Anchor

This thing is 8"/20cm long. I printed diagonally to fit on my print bed.

Included OpenSCAD file allows you to change the dimensions and to remove the flat cutoff part to make the screw whole. I believe that if printed vertically instead of horizontally a weakness in a layer will cause the shaft to break when under load.

You need to print supports because of the tip which doesn't lie flat on the print bed.

Suggestions for improvement welcome.
