Hedge Shears Adjustment Knob

This is a replacement adjustment knob to suit generic, import hedge shears that use an M8 tension adjusting nut. The original design has the M8 nut recessed from the bottom side of the plastic knob which results in quite thin, open ended supports that split and fail prematurely. This design has the M8 nut recessed from the top side and has proven to be a more serviceable design.
I found printing this with the top side of the knob facing the bed made post printing clean-up easier.
