This is the first attempt to use 3D printed servo's for a Delta robot.

I am now working on the Arduino software...


Deltagear.stl

This gear has to be printed 3 times. It fits exactly over one of the standard horns. Please cut of exess of the horns!

Deltatriangle bottom1.stl

This part to be printed once. It is the bottom part of the unit. The wires coming from the servo's should be put through the holes.

  • 3 × TowerPro Micro Servo 9g SG90
  • 12 × Ball links
  • 1 × Arduino
  • 1 × 3D printed parts. Print with accurate sticking to print bed!

    Step 1

    Print the .stl files preferrably without brims, they are difficult to remove. It may be necessary to sand the beams in order to fit.

    Please inform me if the .stl files are not in the correct size....

    When constructing, set the servo's in the middle position, set the beams in the middle position and then fix the gears in their middle position.
