Itty Bitty Double Extruder
Now that I've had a few months of positive experience with the Itty Bitty Belted Extruder (http://www.thingiverse.com/thing:389105), I'm working on a double-extruder version. This is just a teaser--I'm still waiting on some parts to get the prototype up and running.
Features:
- Close nozzle spacing (20mm) maximizes usable bed area
- Integrated wire management--all wires route up through the center of the extruder block
- Compact -- Overall width about 1cm wider than a single Greg's
- Lightweight -- Uses NEMA 14 motors to keep total weight similar to a Greg's
- Low center of gravity -- mass is centered around X belt attach point to minimize X acceleration torque and flex
- Uses standard MakerFarm hobbed bolts
- Uses common 688ZZ bearings
- Easily printable without support
