Extruder Upgrade for 1.75mm E3D-v6 on LulzBot TAZ 4.1

Upgrades a TAZ 4.1 (or similar) to print 1.75mm filament, and with a wider variety of materials—even works great with NinjaFlex! Full PTFE-lined filament path from spool to hobbed-bolt to heat-break. Printing new extruder and idler is required, but other original parts may be re-used. Requires firmware modifications and don't forget to adjust that Z-endstop!
