Overview

The RepRap Wallace is named after Alfred Russel Wallace, who independently discovered the theory of evolution by natural selection after Darwin, but before he published. It is loosely based on the Printrbot, but is a complete redesign in OpenSCAD to be more robust (without the loose press-fit mountings), but still extremely simple. It is designed for use with 6mm smooth/threaded rods and NEMA14 motors like the ones used in the Huxley design, and LM6UU bearings for linear motion, though its parametric nature means that NEMA17/M8/LM8UU versions will also be possible. STLs can be found on thingverse, the source is on Github, and the latest updates/previews can be found on Whosawhatsis' Google+ page. This design is a work in progress.

Parts

In addition to the printed parts, the following parts are required (this is a tentative list, and the parts WILL change before the design is complete):

  • 4 high-torque NEMA14 motors. Sources:
  • 1 set of electronics
  • 1 extruder
  • 3 pairs of 6mm smooth rods (measurements will depend on desired build volume).
  • 2 pairs of M6 threaded rod (measurements will depend on desired build volume).
  • 10 M6 nuts.
    • These can be found locally.
  • 2 M6 nylock nuts.
    • These can be found locally.
  • 8 M6 washers.
    • These can be found locally.
  • 11 LM6UU linear bearings.
  • 3 623 bearings. (6 needed for the double-bearing idlers)
  • 13 10mm M3 screws.
    • These can be found locally.
  • 7 30mm M3 screw.
    • These can be found locally.
  • 2 50mm M3.
    • These can be found locally.
  • Approximately 13 M3 nuts and washers.
    • These can be found locally.
  • 1 sheet of MDF or other flat material (measurements will depend on desired build volume).
    • You can buy this locally and cut to size.
  • 2 belts
    • This could be of type "XL timing belt" like here. Or type "MXL timing belt" like here. It should match your drive pulleys from below.
