Sources are readily available at https://github.com/Lodran/differential_planetary_gearbox. A companion extruder will soon be available at http://www.youmagine.com/designs/pocket-extruder. The design fits either a Nema 17 or Nema 14 motor. Four variations of the gearbox are provided: - gearbox_printed_sun_105.stl - Printed sun gear, 10mm (105ZZ) drive shaft bearing. - gearbox_printed_sun_115.stl - Printed sun gear, 11mm (115ZZ) drive shaft bearing. - gearbox_metal_sun_105.stl - Metal sun gear (See BOM), 10mm (105ZZ) drive shaft bearing. - gearbox_metal_sun_115.stl - Metal sun gear (See BOM), 11mm (115ZZ) drive shaft bearing. Note: Assembly is fairly configurable, so the BOM is more of a guideline than anything else.
