// The actual length of a JHeadMk5 is 51.2 but at the time the kit was designed I thought it was 54. The effect of this is that the
// extension on the Wades block is shorter than it should be so the tip of the hot end is higher so the fan duct needs to be
// fitted a bit higher. This bodge allows the model to reflect reality without correcting the extruder block and changing the firmware.
