3DTMT: 3D-Printed Toddler Mobility Trainer
About this project
The 3D-Printed Toddler Mobility Trainer (3DTMT) is an affordable, open-source device that empowers young children with disabilities to explore their environment independently. Designed for indoor use, it fills the gap in early-age mobility options, especially for toddlers who lack the strength or coordination to crawl or walk and have limited access to age-appropriate wheelchairs. By enabling seated, arm-driven movement, the 3DTMT provides a practical, easily manufactured solution that promotes early mobility, engagement, and development. The 3DTMT was designed in collaboration between LINK PBC, Tikkun Olam Makers, and MakeGood.
The challenge
Many toddlers and young children with disabilities lack the physical strength or coordination needed to crawl or walk independently-- even though they may be ready to explore and engage with their environment. Wheelchair options for this age group are rarely available, affordable, or covered by most insurance providers.
This product helps kids learn to move in a seated position using their arms and/or hands, providing increased mobility for those with limited lower limb strength.
Who it helps
The 3DTMT is an affordable, open-source solution designed to support independent mobility for young children in indoor environments.
