Wanhao/Monoprice Duplicator i3 full filament guide + flex upgrade

thingiverse

This upgrade is designed to keep the filament organized in the print area. The filament is guided through a tube so it does not roll back to the barrel as the extruder moves closer towards it. Additionally no short sample will curl around the print head as it is solidly guided inside the tube. Works only with 1.75mm filament. Also acts as a FLEX UPGRADE for the stock extruder, as the extruderplate is completely replaced with a version that guides the filament deep down into the hotend. You will need 4 screws (4mm) with matching nuts and a length of at least 30mm.
