Free 3D-printed wheelchairs for toddlers.
Every kid deserves to move.
Built For Them has been accepted as a maker with MakeGood's 3D Mobility network. That means I 3D print and assemble Toddler Mobility Trainers - small, modular wheelchairs for young kids - and deliver them to families at no cost. Your donation pays for the materials - about $150 per chair.

What is the Toddler Mobility Trainer?
The TMT is a modular, fully 3D-printed wheelchair for children roughly 2 to 8 years old with limited mobility. It's designed to build independence, coordination, and social connection - letting kids explore and keep up with the world around them.
Snaps together
Assembles without tools or glue. Parts are designed for standard desktop 3D printers.
Reprint, don't replace
If a part breaks or wears out, just that piece gets reprinted - not the whole chair.
Shared freely
MakeGood publishes the full model files and assembly instructions so makers everywhere can help.
Materials for one chair.
Each TMT takes about $150 in materials, plus days of print time. Donations cover the materials so the family never pays a thing.
| Material | Amount | Used for |
|---|---|---|
| PETG filament | 8-10 spools | Frame and most structural parts |
| TPU filament | 2-3 spools | Flexible parts like upholstery and straps |
| Print time | Many days of printing | Donated by Built For Them |
| Assembly | Tool-free | Donated by Built For Them |
| Materials cost to fund | ~$150 per chair | Covered by donations |
