Wade extruder derivate optimized for fast filament change

thingiverse

I engineered this adaptation of the Wade for personal use over a year ago. It doesn't require springs, opting instead for three or four layers of heavy-duty double-sided elastic tape. Also, it omits the short axis needed for the idler, relying solely on a short screw. To build this model, you will need to print with ABS or possibly Nylon. The axis employed in the locking mechanism should be printed from Nylon or vapor-smoothed ABS, as otherwise it won't likely provide enough strength to function correctly. Two holes in the axis require M4 threads to secure the threaded rods.
