Enabled by 3D – Twisty Pen Grip

20160829_3D Print Pen Grip

It’s competition time at MyMiniFactory and I thought I’d use it as an excuse to spend an afternoon creating something new and simple to 3D print. The “#enabledby3d” competition brief calls for an “item that makes an everyday chore easier, or an enabling device, allowing those with disabilities greater accessibility.”

I decided to focus on something most of us take for granted – writing and drawing with a pen. If you have arthritis or some other sort of hand dexterity problems from injury or illness, picking up a cheap standard pen and using it can be frustrating, painful or even impossible. One option is to pay a lot more money for large diameter pens, or buy those slide-on grips which look ugly and draw attention to the fact that you may have grip difficulties.

So what I’ve created is a simple sheath that slides over the full length of a standard Bic pen or similar, significantly increasing the diameter of the pen and changing the geometry so that it may be more easily maneuvered. The sheath prints without needing any support material, and the cheap pen simply sides inside ready to use. What I hope is achieved by this design is something that not only enables people with hand dexterity issues, but something that is appealing to anyone – in this way the design doesn’t seem like an assistive device, but something desirable that someone might be using simply to stand out and be unique. Rotate the model around below to see all the details, particularly the spiral top.

If you like the Twisty Grip head over to the MyMiniFactory page to give it a like to increase my chances of winning the competition! Better yet, you can download this design for free and print it for yourself, or for someone you know who could benefit from it. As soon as the competition ends I’ll also post it to the other 3D printing file sites I normally use, but for now please help share this design and have some fun making it for yourself. Print in bold colours to stand out, or use different coloured materials to designate different pen colours – the choice is yours.
