Planetary Geared Extruder

thingiverse

This is a variant of Nylocke's and Glacian22 EZFlex extruder. It is a direct replacement for Seemecnc's EzStruder. Designed for use with 1.75mm filament and a Nema 17 Planetary Geared Motor. Like Glacian22 extruder, it can handle flexible filaments very well. Nylocke's design: http://www.youmagine.com/designs/ezflexstruder Glacian22's design: http://www.thingiverse.com/thing:744759 I'm not good at explaining the assembly in english, so I hope the pictures can show it clearly. BOM: - (x9) M3x10mm bolt - (x4) M3 nut - (x1) M4x30mm flat head bolt [Arm to Body. It needs to be a flat head bolt, so that the bearing can rotate freely] - (x3) M4 nut (or nylon lock nuts) - (x1) M4x50mm bolt [Body to Mounting Spacer to Mounting Bracket] - (x1) M4x40mm bolt [Body to Mounting Spacer to Mounting Bracket] - (x2) 684ZZ bearing (9mm OD, 4mm ID, 4mm thick) - (x1) 625ZZ bearing (16mm OD, 5mm ID, 5mm thick) - (x1) EzStruder Spring [don't know the specs] - (x1) Passthrough Push Fit Connector - (x1) Nema 17 Planetary Geared Stepper Motor (recommended ratio of 5:1) - (x1) M7 hobbed gear for 8mm shaft - 7cm aprox of PTFE Tubing (2mm ID x 4mm OD) Printed Parts: - Body - Planetary Adapter - Arm - Bearing Holder (you will only need one. There are 4 with different diameter so you can choose the perfect fit) - Spring Tensioner - OPTIONAL: Mounting Spacer (for using M4 bolts instead of the 6-32 from seemecnc. You will need to drill bigger holes to the EZStruder Mounting Bracket)
