For hundreds of hours, Zac did exactly that.
Built for One Particular Little Girl
The final mobility chair was not generic.
It included details intended specifically for the toddler who would receive it.
Multiple reports describe pink accents chosen because pink was a favorite color associated with the child.
That may seem like a minor detail, but it represents something important about assistive design.
A mobility device is not simply a mechanical object.
It becomes part of a person’s everyday life.
People see it.
They touch it.
They sit in it.
They move through the world with it.
Making a device attractive and personal can therefore be part of treating its user as an individual rather than as a medical problem to be solved.
The chair also included practical features.
Reports on the project describe a removable tray table and cup holder, space for medical equipment and adjustable components such as the headrest and footrest.
MakeGood’s own catalog confirms that the Toddler Mobility Trainer system is designed with modular and practical components, including tray-table options and 3D-printable parts intended to support young users.
The adjustable elements were particularly important.
A 21-month-old child will grow quickly.
A device that works today but becomes unusable a short time later would have limited value.
By incorporating components that could be repositioned as the child grows, the project was designed with the future in mind.
Instead of asking only, “Will this fit her now?” the design also considered, “How can this continue helping her later?”
That is thoughtful engineering.
And it came from a 13-year-old.
More Than a School-Level Project
What makes Zac’s summer stand out is not simply his technical ability.
Young people regularly build impressive things.
Students create robots, write software, launch science projects and experiment with engineering.
Zac’s project had an additional dimension.
There was a real person at the other end of the work.
If a decorative print failed, it might be frustrating.
If a mobility component failed, it mattered.
That difference changes the way a maker has to think.
Comfort matters.
Durability matters.
Adjustment matters.
Accessibility matters.
Safety matters.
The user matters.
That is the fundamental idea behind assistive technology: technology is valuable not merely because it is sophisticated but because it improves someone’s ability to participate in everyday life.
The World Health Organization defines assistive technology broadly as products and related systems that help maintain or improve people’s functioning and independence. Appropriate mobility equipment, including wheelchairs, can improve access to daily activities, education and social participation.
Zac’s chair was a small example of that much larger global need.
A Worldwide Problem of Access
The need for assistive technology is enormous.
According to the World Health Organization, approximately 2.5 billion people worldwide need at least one assistive product.
That figure is expected to rise beyond 3.5 billion by 2050.
Yet access is highly unequal.
WHO says access to needed assistive products can be as low as 3 percent in some settings, with cost, limited availability, lack of financing and shortages of trained personnel among the barriers.
Those statistics help explain why groups such as MakeGood focus on open designs and 3D printing.
Traditional assistive technology can sometimes be expensive, difficult to customize or unavailable in particular communities.
Digital fabrication offers another possibility.
A design can be created in one place, shared online and printed somewhere else.
A component can be modified instead of requiring an entirely new product.
A volunteer with the right equipment and knowledge can potentially become part of the manufacturing process.
MakeGood’s website says its mission is to create free, custom assistive devices for people with disabilities, while its device library allows makers to download designs without charge.
That model turns people with 3D printers into potential contributors to accessibility.
Zac became one of them.
Technology With a Human Purpose
There is constant discussion about how much time young people spend with technology.
