CTC/Makerbot/Flashforge extruder - flexible filament upgrade

prusaprinters

<p>Redesigned extruder block with smaller drive gear hole (11.8 instead of 13 mm) -&gt; longer filament support between the drive gear and hot end so flexible filament does not get stuck in between.</p> <p>As CTC that I own is an Makerbot Replicator 1 (dual) clone, it should also work for Makerbot Replicator 1 and FlashForge printers.</p> <p>Update 01.04.2015: Changed hole diameter to 11.8 so it does not need sanding, moved filament hole a bit, made a bigger diameter hole on the bottom so it does not touch the gear fastening screw</p> <p>Update 31.03.2016: as no changes have been made for a long time I'm unchecking the WIP marker of this thing</p> <p>Update 26.06.2015: now 2 files are available: for left and right extruder</p> <h3>Print instructions</h3><h3>Category: 3D Printer Extruders Print Settings</h3> <p><strong>Printer:</strong> CTC - Makerbot 1 (Dual) clone</p> <p><strong>Notes:</strong></p> <p>Best printed in ABS or Nylon as even the cold end of the extrude can get quite hot on some printers and with some materials.</p>
