Sheepdog's Linear Bearing RepStrap - Wood Version

RD H.
This unit is intended as a 3D printer that can be built without printed parts. Medium Density Fiberboard (MDF) and fabricated PVC parts are used with steel rod and standard hardware; the print deck is sheet metal and aluminum angle. Operation: the lightweight print platform moves in both X and Y directions, and the extruder head simply moves up and down on the Z axis. X and Y axes are belt-driven, using inexpensive linear bearings; Z axis is similar to Mendel, and uses belt-driven threaded rod. Most wood parts could likely be made from plywood, acrylic or sheet metal. PVC parts, which are formed with saw and drill press, could also be CNC machined; they could be made from other materials such as layered plywood, or they could be molded or printed. Pulleys could be printed to keep costs down, but those used here are purchased. There's plenty of space on the machine's base to mount necessary electronics. A sheet metal version of this unit is also in the 3D Warehouse.
