    The palm pen holder is a low-cost, 3D-printed writing splint that slips onto the palm. Users can gently curl their fingers around a handle to hold it securely or hook their thumb around the writing utensil. This 3D Printed Assistive Device has a large hole that can accommodate various writing tools width. This device is useful for those who have some grip and strength in their fingers.


    My first attempt at a [Customizable Palm Pen Holder]( is up on Thingiverse. You can use Makerbot Customizer on that site (or more flexibly, from inside [OpenSCAD]( on a local machine) to customize all major dimensions plus the inscription.

    My model’s a bit rough and has had no user testing.


    I’m pleased to say that this model has had some user testing from one user who has requested lots of custom variants. It can now handle much larger pens, in theory up to 22 mm diameter. You will need to make the device thicker to compensate if you do this, though.

    Github gist backup of the code if Thingiverse is being unreliable:

    Sample parameter set:

    “hand_width”: “72”,
    “lefty”: “false”,
    “pen_dia”: “20”,
    “pinkie_thick”: “28”,
    “strap_width”: “25”,
    “thumb_thick”: “35”

    I am an Occupational Therapist working in Toronto. I found your wonderful Palm Pen Holder on the web, and I would like one for an adult male patient.  Your help is much appreciated.
