OB1.4 Dual E3D extruder
thingiverse
I redesigned a carriage and extruder setup for the OB1.4 printer, accommodating dual extruders on the X carriage. The geared stepper motors for filament driving can be purchased from RobotShop. Bowden tubing and hobbed filament drive can be found at SeeMeCNC and TrinityLabs, respectively. Tubing fittings are available at SeeMeCNC as well. A 624 bearing is used for the idler in the extruder, while a single 40mm fan with a common duct cools both hot ends instead of stock 25mm fans. An update to the motor mount uses 2mm PTFE tubing to prevent filament buckling at higher print speeds. A video demonstrating the dual extruder setup is available here: http://youtu.be/H1djLu2qJlc.
