My Human Kit develops inclusive, open-source prosthetics and assistive devices tailored to the real needs of people with disabilities. By combining 3D printing with collaborative design, they create affordable, functional, and personalized solutions—from bionic hands to custom wheelchair accessories—empowering users and pushing the boundaries of assistive technology.
CHALLENGES:
Limited access to advanced, personalized prosthetics due to restrictive healthcare reimbursement policies.
Lack of affordable, specialized assistive devices for daily life and leisure activities.

About the Company:
The My Human Kit association embodies a new approach to social and technological innovation by using digital manufacturing to support people with disabilities.
Based in Rennes, the organization brings together people with disabilities, makers, healthcare professionals, and engineers around a common goal: to co-design and produce personalized, accessible assistive devices.
By placing people at the heart of the process, My Human Kit transforms beneficiaries into active participants in creating their own solutions.
One of its flagship projects is the Bionicohand—an open-source bionic hand conceived and championed by Nicolas Huchet, co-founder of the association and a forearm amputee. This prototype combines 3D printing, accessible electronics, and a drive for autonomy, perfectly embodying My Human Kit’s inclusive, DIY philosophy.
Overview of Project
About the Project:
Overcoming Challenges:
The Bionicohand project was created with the goal of pushing these limits. Its aim is to provide amputees with an affordable prosthetic hand capable of moving multiple fingers, allowing them to perform a wider range of gestures and activities. Positioned at the intersection of technical innovation and social commitment, the project embraces the open-source model to make more advanced prosthetics accessible to all.
This very approach made it possible for, a young amputee, to receive a customized functional prosthesis. His prosthetic hand is the result of an interdisciplinary collaboration between several partners: a prosthetist (OPR – Orthèse Prothèse Rééducation), a design agency (Make Sense), the Inria research center, and the 3D printing company Sculpteo.
The design files for the Bionicohand are freely available on the project’s website. True to the spirit of open-source development, anyone is free to reuse, modify, or improve these files—whether to manufacture parts, suggest enhancements, or contribute to the evolution of the device. It’s an open, participatory initiative focused on empowering people with disabilities.
Beyond functional or medical prosthetics, there is a growing need for leisure prostheses, designed for specific activities such as cycling, playing a musical instrument, practicing a sport, or simply performing everyday tasks more comfortably. Yet access to these devices remains limited. Often expensive, not covered by national healthcare systems, or simply unavailable on the market, they force many amputees to abandon certain passions or come up with DIY solutions. This reality highlights the importance of open, collaborative projects that make it possible to imagine and create prosthetics tailored to real-world uses—closely aligned with each individual’s needs and aspirations.
Future Developments:
As part of its mission to promote inclusive innovation, My Human Kit is leading a project in partnership with the Edulab fablab at Rennes 2 University called “Don de main” (a play on words meaning both “Gift of a Hand” and “Hand Donation”). This event invites participants to have their hands 3D-scanned, with the goal of building an open-source library of 3D-printable hand models. The database aims to offer aesthetic and customizable prosthetic hands, enabling users to benefit from solutions better suited to their body and identity. With this approach, a prosthesis becomes not only functional but also a means of personal expression.
In the area of mobility, the association is also working on improving and customizing wheelchairs, allowing users to personalize their equipment by adding specific features. These can meet particular patient needs, such as motorizing the chair or adding comfort and safety accessories like mirrors, footrests, cup holders, or other ergonomic enhancements.
Through the Notaboo project My Human Kit is collaborating closely with Sculpteo to optimize the design and manufacturing of the nozzle for a mobile Japanese-style toilet system. Originally produced using FDM 3D printing, the nozzle was prone to leakage due to weak inter-layer adhesion. With Sculpteo’s expertise and access to SLA resin printing, this issue was resolved by eliminating micro-leaks inherent to the original printing method. Additionally, Sculpteo has supported the redesign of the threading and the integration of a silicone seal, improving the watertightness of the assembly and ensuring it can withstand regular use. This technological synergy aims to produce a more reliable, durable nozzle aligned with Notaboo’s goal of promoting greater autonomy.
In parallel, the association continues to develop orthoses and prostheses tailored for specific uses—especially for sports like swimming, cycling, and other physical activities that require custom equipment. These devices are co-designed with direct input from end users to meet their individual needs as closely as possible. Sculpteo contributes its 3D printing expertise to help turn these ideas into practical, durable, and accessible solutions—ultimately improving quality of life and fostering inclusion through technology.
