Planetary Geared Extruder

thingiverse

This is a custom-designed extruder, based on Nylocke's and Glacian22's EZFlex variants. It replaces Seemecnc's EzStruder directly. The design is intended for use with 1.75mm filament and a Nema 17 Planetary Geared Motor. Like the Glacian22 extruder, it handles flexible filaments well. Nylocke's design can be found at: http://www.youmagine.com/designs/ezflexstruder Glacian22's design is available on Thingiverse: http://www.thingiverse.com/thing:744759 I'm not skilled at explaining assembly in English, so I hope the pictures provide clear guidance. Bill of Materials: * (x9) M3x10mm bolts * (x4) M3 nuts * (x1) M4x30mm flat head bolt [required for arm-to-body connection, with a flat head to ensure free bearing rotation] * (x3) M4 nuts (or nylon lock nuts) * (x1) M4x50mm bolt [for body-to-mounting spacer-to-mounting bracket connection] * (x1) M4x40mm bolt [for body-to-mounting spacer-to-mounting bracket connection] * (x2) 684ZZ bearings (9mm OD, 4mm ID, 4mm thick) * (x1) 625ZZ bearing (16mm OD, 5mm ID, 5mm thick) * (x1) EzStruder Spring [ specifications unknown ] * (x1) Passthrough Push Fit Connector * (x1) Nema 17 Planetary Geared Stepper Motor (recommended ratio of 5:1) * (x1) M7 hobbed gear for 8mm shaft * Approximately 7cm of PTFE Tubing (2mm ID x 4mm OD) Printed Parts: * Body * Planetary Adapter * Arm * Bearing Holder [choose one with the perfect fit from four available options] * Spring Tensioner OPTIONAL: Mounting Spacer [for using M4 bolts instead of the 6-32 from seemecnc; requires drilling bigger holes in the EZStruder Mounting Bracket]
