Wanhao Duplicator 6 Monoprice Ultimate Filament Sensor

Added a funnel guide so that it is easier to load the filament without turning the printer around, a rim so that the halves lock better together and a bypass for flexible filaments. I had to bend the lever as shown and ad a little pedestal to get the filament to go in easily. This works with the Marlin version for the duplicator 6 . When the filament runs out the printer stops and lets you change the filament and to continue where it left off. Works great.
