The fixed file fixes the head being connected to the body.

This print is very costly in terms of filament I recommend printing just the file called Leg test first to see if your printer can print the collapsing segments 

Print setting, 0.4mm nozzle is required, Make sure your line width in cura is set to 0.5mm and extrusion width is set to 0.5mm in prusa slicer for perimeters 

Support aren't necessary and I printed at 0.30mm draft setting with 5% grid infill

The Blender file is messy but I have all the cutouts labeled.   Please let me know
