School Locker 3D Printing Hack

"Creativity, as has been said, consists largely of rearranging what we know in order to find out what we do not know. Hence, to think creatively, we must be able to look afresh at what we normally take for granted." — George Kneller

These New Jersey students were not afraid to get creative. They saw a need of a fellow classmate and knew they could alleviate it. With quite a few prototypes, some time and creativity, they were able to help a younger student with a task that many of us take for granted.


NJ Students Design 3D Printed Handle to Enable a Disabled Classmate to Open Her Locker


Sometimes physical activities which might seem like simple, everyday tasks are more difficult than they appear for some people. A senior at Newton High School in New Jersey, Justin Hermann, is one of those who take notice of the people around him, and Hermann used 3D printing to lend a hand to a fellow student.

Hermann had noticed that one of his freshman classmates was having a hard time opening her locker, and that gave him an idea.


He saw that the hallway lockers are designed in such a way that opening them requires a user to pinch the handles and lift them. The freshman in question faced a physical challenge which made that seemingly simple task a real headache.

So under the mentorship of technology teacher Brian Bennington and with the help of junior student Robert Borgognoni, the trio used 3D printers available them in their advanced principal design class to create a plastic handle to modify the student’s locker.

Borgognoni took on the task of designing a plastic cover for the handle inSolidWorks, while Hermann provided the conceptual framework for the project.

“We went through multiple prototypes,”

Borgognoni told the New Jersey Herald.

The pair took three weeks to design and produce the final product, and the last iteration of the print took nearly a full day to output.

Hermann said working on the project opened his eyes to what 3D printing technology can do when correctly applied.

Newton High School has a pair of MakerBot 3D printers, and according to Bennington, having the machines on-site allows his students to think differently, and that’s led them to explore new ideas on their own initiative rather than waiting for an assignment..

“For a teacher, that’s like a dream,” Bennington said.

The handle is attached to the locker with a bolt that passes through it, and that allows for the device to essentially bypass the latch.

The design has been in use since the beginning of November, and Hermann and Borgognoni say their classmate simply has to slip her hand in the device and pull to open the locker open. When not in use, the locker stays shut via magnets installed to take care of the job.

Bennington adds that 3D printing solutions haven’t been limited to Hermann and Borgognoni’s project. He says the 3D printers have also produced a trumpet mouthpiece for the music department.

The technology has also provided the students with a vision of their futures after school as well.

“This project made me realize that what I want to do is open up my own company for biomedical engineering. What I want to do is mass produce products and inventions to help handicapped people,” says Hermann.

For his part, Borgognoni says he plans to pursue further studies in the engineering field.
