Ultra-Bot 3D Printer
by wjsteele, published
The Ultra-Bot 3D Printer is a beautiful printer inspired by the original Makerbot Cupcake. The changes over the original Cupcake are numerous, however, following the same instructions, it should be easy to figure out. The Ultra-Bot utilizes a design similar to the Cupcakes X/Y stage to move the extruder over a build platform that raises and lowers on the Cupcake style Z-Stage. The Z-Drive is inverted and tucked in the lower portion of the printer to make it less fragile. The extruder has been switched to a bowden style extruder with the drive system located in the lower portion as well.
Here is a video of it printing. https://www.youtube.com/watch?v=bXYxcn2U-6k

Assembly of the printer follows that of the original MakerBot Cupcake. See the pictures for the main differences.
EDIT: It was pointed out to me that I forgot to upload add a few pieces. I've attached the bowden clips (both hot and cold ends) in a seperate DXF file. Also, the black delrin spacer for the extruder drive is directly from the Makerbot MK5 extruder (http://www.thingiverse.com/thing:3290)
