About COCRE HUB
COCRE HUB is a co-creation platform for making assistive devices (self-help devices) that fit each person, using 3D printers.
Purpose and key features
Our purpose is to turn "can't" caused by disability or aging into "can" through technology and co-creation. We respond to individual needs that mass-produced products cannot reach, aiming for an inclusive society where everyone can live in their own way. The platform offers the following features.
Sharing 3D data: We publish 3D models of a wide range of assistive devices (more than 340 as of January 2026), which anyone can download and use for free.
Easy size adjustment (parametric models): Without special knowledge, you can adjust the size on the web and create data shaped to fit you.
A connected community (Collaborator Map): A worldwide map connects people who want to make something with people who can make it and specialists who can give advice, so you can get advice and prints close to home.
Sharing knowledge and cases: We publish how to use 3D printers, making know-how and real-world cases, and support the training of engineers and supporters.
Notes on using the 3D models shared on this service
We aim for a society where everyone can be creative and freely develop technologies such as 3D printing. To make this possible, all data is supported by the passion of creators and the cooperation of the community.
When using data from this service, neither the designers nor the platform can accept any responsibility for devices made with the shared files. Please use them after discussion and agreement between the users and the makers.
Intellectual property in the 3D models shared on this service (COCRE HUB COMMONS LICENSE)
- These files may be used freely for the following purposes:
(1) Use by the people who need the device themselves (people with disabilities, supporters, therapists)
(2) Use in the care of individual cases, including occupational therapy practice
(3) Use as teaching materials or exhibits
(4) Free distribution by schools and related organizations for outreach and promotion
(5) Use in research and development or conference presentations - Within the scope of 1., the 3D models may be modified.
- Posting STL or other files on other platforms or services without permission is not allowed.
- For sales or other commercial use, please contact us first.
Credit is generally not required for uses (1) to (5) in 1., but it encourages us if you mention that you use COCRE HUB or include its URL. We also welcome reports on how you have used the models. Please write to us at the address below.

COCRE HUB assessment criteria for publishing models
COCRE HUB applies its own assessment criteria, based on academic research, to the 3D models it publishes.
Five items (suitability of material, achievement of function, usability, appearance, and durability) are rated on a five-point scale, and the need for individual adjustment is also checked.
By publishing only the models that pass this assessment, we build a reliable database that can be used with confidence in practice.
Assessment items
| Item | Viewpoint |
|---|---|
| 1. Suitability of material | Flexibility, hardness, safety, hygiene, etc. |
| 2. Achievement of intended function | Does it fully provide the intended support or assistance? |
| 3. Usability and comfort | Simplicity, ease of handling, low burden |
| 4. Appearance and acceptability | Is it a design the user wants to use? |
| 5. Strength and durability | Is the structure strong enough for daily use? |
| 6. Need for individual adjustment | Does size, angle or shape need to be optimized for the individual? |
Items 1–5: five-point scale
| Score | Rating |
|---|---|
| 5 | Very good |
| 4 | Good |
| 3 | Neutral |
| 2 | Poor |
| 1 | Very poor |
Item 6: need for adjustment
Checked as "yes" or "no". If "yes", it is handled in one of the following ways.
- Size variations such as S / M / L
- Individual adjustment with a parametric model
Decision criteria
For items 1 to 5, the following steps are always taken when the score is 1 or 2, and taken after judging the need when the score is 3.
- Revise the design and data
- Make and evaluate a new prototype
- Re-check with users and professionals
- Make it parametric if needed
- Decide on publication after reassessment
Examples
| Case | Typical example | Action |
|---|---|---|
| All items 4–5 | Mature model | Publish immediately |
| Only one item is 3 | Minor adjustment | Publish after revision |
| Several items are 3 | Design not yet mature | Redesign |
| Any item 2 or lower | Safety concern | Not published |
