3D Printed Pen/Marker Holder

thingiverse

Many people with disabilities such as cerebral palsy (not limited to CP) can grasp with their hand but not rotate at the wrist. This means that they can not draw or write on paper, as the the pen is usually parallel to the paper. This device is designed to hold a pen or marker vertically while being held itself horizontally. By loosening the thumbscrew, the pen or maker can be switched out at will. It uses a captive square nut and a thumbscrew to help maintain the pressure on the marker. The openSCAD file can be adjusted for different diameters, finger grip positions, etc.
