Geared Bowden Extruder 20 20 Mount
thingiverse
This is a remix of my other extruder (https://www.thingiverse.com/thing:1758044). I've tweaked the design slightly and made a mount to fit on a 20/20 extrusion using M4 bolts. All hardware is as per a standard Wade's Geared Extruder, detailed on my other listing (http://reprap.org/wiki/Wade%27s_Geared_Extruder#Non-Printed_Parts). UPDATE: I've now included an STL called "Support 20 20 Inserts". It's designed to take M3x4x4 brass inserts such as http://www.ebay.co.uk/itm/M3-4-4mm-Knurled-Nuts-Thumb-Nuts-Insert-Embedded-Nuts-Brass-Solid-/122521132059?var=422958194833&hash=item1c86d41c1b:m:m5b193TN0FY7KhARXg5rmqA. These make fixing the idler block to the motor mount/support easier. The holes are intentionally too small, so I melted the inserts into the plastic by heating them with a soldering iron.
