Laila holding two 3D-printed prosthetic arms

I print

the world.

I'm Laila El Moselhy, a 16-year-old volunteer with e-NABLE, an open-source community that designs and 3D-prints upper limb prosthetics for people who need them, at no cost. Every case is a real person. Every arm is built by me, from scratch, in my home.

What is e-NABLE?

A global network of makers doing something remarkable

e-NABLE is an open-source community of volunteers, engineers, hobbyists, students, teachers, who design, print, and donate 3D-printed upper limb assistive devices to people who need them around the world. No fees. No waiting lists for those who qualify. Just people with printers helping people who need hands.

I joined e-NABLE as a volunteer when I was 14. Since then, I've taken on cases from the Philippines to Morocco, building each prosthetic from raw filament in my own home and shipping it to someone I've never met.

8,000+

Devices delivered worldwide by the e-NABLE community

$50

Approximate cost of materials per device, compared to $5,000–$50,000 for a commercial prosthetic

Open

All designs are freely shared and open-source, so any volunteer can build any approved device

How it works

From a message to a finished arm

Every case begins with a person, somewhere in the world, reaching out to e-NABLE. From there, I take it step by step.

01 Contact

A recipient or their family contacts e-NABLE. Cases reach me through the community platform or direct referrals from other volunteers.

02 Measurement

I guide families through a home measurement process, arm tracings, photos against a wall tape, and specific dimension captures, to calibrate the design remotely.

03 Build

I select and scale an approved e-NABLE design, print all components, source the hardware (Velcro, cord, bolts), and assemble the prosthetic by hand.

04 Ship & follow up

I ship the finished device to the recipient, then follow up to confirm fit. If adjustments are needed, I print replacement parts and send them.

Featured Case

Case 001 · October 2024

K.

Philippines

K. was 11 years old when he lost his right arm to electrocution. A friend found e-NABLE online and reached out, there were no local volunteers in the Philippines. His message found me. He was my very first case.

Not knowing which design would suit his residual limb, I built him two prosthetics, a gold model and a blue model, and shipped both. He picked the gold one. Eight weeks of printing, calibrating, and international shipping later, K. danced in the hallway of the fitting office on the day it arrived.

Support the work

Help me reach the next person.

Every arm costs around $50 in materials. I've been covering that myself, but donations to my GoFundMe for Hand in Hand — the nonprofit where I first trained — go directly toward printing prosthetics for people who need them and can't access commercial options.
