Knob for Kenwood range cooker

Replacement plain 8mm dia. D-shaft knobs for Kenwood CK 405 range cooker. I assume they would work for anything else with that spindle!

FreeCAD file included in case you want to add numbers or symbols. I'm still working out how to do that…

Print spindle down with supports. I used 40% cubic infill and they seem plenty strong enough for their purpose.

[EDIT] Gcode uploaded with 4 walls and 15% infill, as no apparent need for higher infill with more walls.
