  1. Laser cut body from 3mm plywood and assemble with glue (the finger joints in the attached dxf actually do not fit perfectly together)
  2. 3D print nozzle (we used the 12.5 mm exit diameter) and wheel spacers.
  3. Put axles through body. Our axles were 1.5mm diameter.
  4. Put wheel spacers and wheels on axle. hot glue wheels to axles.
  5. Tape nozzle to body.

Things about this design that should be fixed that were never fixed because it's hard to spend the Time to make a thing Good when you have 5 other classes to do work for. Such is school.

  • The holes in the base of the body are too large; marbles fall through. Our jerry-rigged solution was to cover the holes with a piece of paper.) 
  • Short walls (front and back) of body were incorrectly drawn; the finger joints don't fit perfectly.
  • The nozzle should be attached without tape.
  • Wheel spacers could be smaller in diameter (for better fit on axle).
