How to request a custom 3D-printed mobility accessory
Start with an everyday task, then share equipment details and measurements. Here is what a useful accessory request looks like.

From the initiative building this library. This guide describes accessory planning, not an assessment of your equipment.
Describe the moment you want to change
You do not need a CAD file or a product name to begin. “I want my phone nearby while I am sitting outside” is more useful than guessing which bracket you need. Explain where the item should sit, how you want to reach it, and what gets in the way now.
Mission Printpossible is a Chicago initiative developing personalized, free-of-charge accessories for mobility aids. Our website is currently a preview of that process. A saved request confirms that the idea was recorded; it does not guarantee production, eligibility or a response time.
Choose a starting point, or bring a new idea
The library gives you a few shapes to discuss: a bottle holder, a grocery bag holder and a small tray / phone holder. Rotate a model, pick a color and use “Discuss this design” to carry the selection into the request form. A color choice changes the preview, not the dimensions.
If none of the examples matches your need, use the general request form. Explain the task in your own words. We do not need a diagnosis or medical records to understand an accessory idea.
Bring equipment details into the conversation
Include the equipment brand and model if you know them, but also explain the possible mounting location. Measurements should come from that location, not a similar-looking frame on the internet. If the proposed accessory holds something, measure that item with any case, sleeve or handle attached.
We’ll review how the attachment could fit and whether we can make it. Some requests may need more information or a different approach; others may be outside our capability. We’ll let you know either way.
Keep the conversation connected to your request
Save the reference shown after submission. It helps staff find the original idea and selected design. We’ll email you a confirmation, and our team keeps notes and progress with your request. Reply to the confirmation if you’d like to add anything.
Other assistive-technology services may also be useful. The University of Illinois Chicago Assistive Technology Unit describes support with commercially available, modified and custom equipment. It is a separate organization, not a Mission Printpossible partner; ask it directly about services and eligibility.
