This scad adds a greg-style support shelf to the edge of the turret piece to allow for the required overhang with no other support material. Note that this thing will likely become obsolete when (if?) 3dYeti updates his (awesome) design. Instructions Enter your layer height into the scad, compile, export and print. Snap the support piece off after the print. Or you can download the pre-made one, it's compiled for a layer height of 0.3mm. It may work for you, run it through your skeining tool and make sure there's one layer going across to the support structure to hold up the rest of the print.
