uniX-Wade Universal Extruder

thingiverse

A comprehensive redesign of the Wade extruder has been made, including improvements to fit all printers with 50mm mounting holes (tested only on uniX-Carriage and Orca). Thanks to Daniel for his ideas and testing. The stepper motor has been moved to the bottom, and the idler now includes a tube holder. The filament inlet is closer to the bolt, and it's optimized to work with uniX-Carriage (http://www.thingiverse.com/thing:25420). Additional features include support for 1.75mm and 3mm filaments and compatibility with J-Head/Groovemount/Reprapfab/Geeksbase/Mendelparts V9/10, as well as many other hotends. Some unnecessary mounting holes have been removed. For the main parts, you'll need: * 1x M8x50/60mm hobbed bolt * 5x M8 washer * 2x M8 nut * 1x 8x20mm bolt (or cutoff of a M8 bolt) for the idler * 2x M4x60mm screw * 2x M4 washer * 2x M4 nut * 2x spring (5mm diameter, 10mm length, depending on strength) * 3x 608 bearing * 3x M3x30 screw (one for the idler, two for the inset) * 3x M3 washer * 4x M3 nut * 1x M3 worm screw (?) * 4x M3x10mm Screw (for stepper mounting) * 2x M4 Nylock nut's for mounting the wade * 2x M4 Screw, length depending on carriage type Additional parts for Mendel-Parts V9/V10: * 1x 28x32x2mm thick metal plate, cut and drilled to fit into the printed "carrierplate" and then drill the holes * 1x M6 brassnut * 2x M4 Nylock nut * 2x M4x15 screw For 1.75mm filament printing, you'll need a brass tube with d=2.4mm/D=3mm. There are two versions of the insets, one with 16.7mm for well-tuned printers and one with 16.4mm for less well-tuned ones. For mounting the extruder to the stock Orca V40/42 metal plate, you need to drill an additional hole (http://www.thingiverse.com/image:136320) and change the screws on the back to countersunk screws. For Mendel-Parts Hotend on uniX-Carriage, you'll need to print an iron or steel plate (28x34x2mm). Print the "carriertemplate.stl" and put the plate into it to mark where the holes should be drilled. Make the middle hole about 7mm and the outer 4.5mm. The iron plate is not needed anymore; just print the new short V9 inset (maybe a second time for filling the hole on the upper side) and screw it tight between two nuts (like shown on the picture), ensuring that the indentation of the inset stands in the right direction. If you want to use 1.75mm filament, you'll need a brass tube with inner diameter 2.4mm and outer 3mm (http://www.conrad.de/ce/de/product/222337/). First, put the extruder with the hotend together, measure how deep the filament hole from the middle of the bolt to the hotend is, and cut it a little bit shorter. Rasp the upper end sharp as shown on the picture. Ensure that you smooth the edge of the upper side or the filament will cut into the insert!
