3FPD-Replicator 2X - Extruder Upgrade - REV4

thingiverse

The Replicator 2X extruder has been upgraded to accommodate flexible filaments, using a highly modified Recreus Hot End kit with specific adjustments. The upcoming REV5 extruders will boast a newly modified Fan Duct REV2 with an improved cooling tube, enhancing the cooling around the filament in the extruder area before it feeds into the hot-end tube. This base is fully printable without supports, while the arm requires only external supports for the bearing slot. The arm integrates the feed tube mount as well, and tension spring geometry has been improved. Using 5/32" and 1/4" bits ensures tight clearance in bearing/arm pivot holes. Makerbot hardware kit components are required for assembly, with pre-assembly taking under two minutes each. L and R extruder parts are included, labeled with a common pin. Feedback is appreciated to continuously improve the design.
