thingiverse
This pen holder is designed specifically for Norland Research Calculator Controlled Robots (http://www.smallrobot.com/). It accommodates standard full-size Crayola markers with a diameter of approximately 14.5mm. A spring hinge bridge between the clamp and base maintains consistent pen pressure despite surface irregularities. Printing takes around 15 minutes on a MakerBot #322. Utilize it for robotic drawing tasks on large papers or as a versatile desk pen holder. Easy shapes like circles are ideal for practice.
