Greg's Hinged Accessible Extruder
by GregFrost, published
This is an update to my Accessible Wade's Extruder.
The idler is now hinged using an M3 screw. I have also added support for the central part of the 608 idler so that there is no need to use washers to space the bearing away from the plastic.
I have been using this design for a while now and love it.
Changing filament is a simple as compressing the spring then whipping out the old filament and poking the new one in.
UPDATE: 6 Aug 2011 - Add arcol (cory75 thing:10532) and wildseyed hotend mount options. Im not overly happy with the asymmetry of the arcol option.

simply call the wade module like this (which is how the included stl was made):
If two mounts have compatible holes, you can include the holes for both like this:
Once it is printed, you will need to trim off the little support piece for the idler hinge and drill the support membranes from the hobbed bolt hole and motor mount holes.
