This is a chuck pen holder for the Makelangelo 3
thingiverse
The Makelangelo 3.0 utilizes an off-the-shelf pen holder that's causing mounting issues due to its lip, which makes it hard to secure easily. I've come up with this customized chuck and holder, attaching directly onto the servo horn via screwing. This new attachment offers a smooth and convenient way to handle the pen. Instructions: First, print out the two chuck pieces separately. Mount one of them with an arm collar onto the servo's mechanical limb. Then attach the servo itself to a plate. Next, slide in your chosen writing tool and its supporting collar. Tighten it firmly until your marker or Sharpie is properly clamped in place. Note: To utilize this design fully, you'll require a modified support plate version.
