The prints need to be done with a dual extruder for the board, using a .4 or.5 mm nozzle at .25 mm layer height with support at 1.5 mm spacing maximum
For assembling the board you would need 3.5 mm smooth rod or 4mm threaded rod.. Also you would need 3mm x 6mm x .3mm springs for the joints ( can be replaced by one found in ball pens ) the white and black parts of joint 2 might need to be glued.
You would need to assemble the files for the dual extrusion as I have separated the black and white colour...
mod 1 and joint 1 need to be printed twice. Rest have to be printed once
