Girl invents way to get new attachments for her 3D printed arm

About the solution

Jordan had the help of her prosthetist, David Rotter, and from Sam Hobish, a designer from Autodesk. Together they combined a medical-grade prosthetic arm with 3D printed attachments at the wrist.

The girl has been working with David since she was three, and together they had the idea of creating a traditional prosthetic arm with a connection at the wrist for screwing in a 3D printed hand. The printed hand then connects with string to a shoulder harness, the kind that Jordan already uses to control her standard prosthetic hook. By moving her shoulder, Jordan can control the hand's grasp.

This means that Jordan's prosthetic doesn't need to always have a hand in her prosthesis. It can be a hook or anything that inventor decides to 3D print and attach to the 3D printing arm. The inventor just needs gluing on a compatible screw if she wants to connect future different creations, which she says she can buy at any hardware store.

To move and control the 3D printed hand, the user can simply move their shoulder to trigger a string that connects the 3D printed extension to a shoulder harness.

According to the inventors, this may be the first hybrid prosthetic arm made of medical and printed parts, so in a sense Jordan has made her way to the cutting edge as the worlds of medical and 3D printed prosthetics start coming together.

Jordan started working using the designs provided by Enable and then Autodesk and Dremel gave her a 3D printer to use at home, and Awesome Without Borders chipped in $1,000 for filament.

"She came with the challenge because she and Sam were trying to figure out a way to use those standard 3D-printed hands, and it got pretty aggravating. She realized that it was not possible with any of the current 3D printed design concepts, since she doesn't have an elbow", explained Jen Reeves, Jordan's mother.

Jordan is now thinking of developing a portable tool that could help people with disabilities to use paper-towel dispensers more easily.

The inventor's mother founded a nonprofit called Born Just Right, which aims to help disabled kids and their parents to learn about design and connect them with organizations that want to get involved in this process.

About the author

Jordan Reeves, born in USA, was only eleven 11 years when she upgraded her 3D printing hand and harm with new 3D printing attachments, in 2017. Jordan was born with a left arm that stops just above the elbow. The girl came up with this solution because the 3D printing designs available weren't fit for her needs.
