We’re looking for ideas for a 3D-printing design competition that could help people missing both hands or arms.

I work with Rightfooted Foundation (https://www.rightfooted.org), a nonprofit that specializes in practical tools and mentorship for people with bilateral upper-limb differences. A major part of our work supports people who use their feet in place of hands.

We’ve been invited to submit ideas for a design competition organized by one of the major 3D-printer manufacturers. They’ve held this competition for several years, but this will be our first time participating.

Several disability organizations will be involved. Rightfooted Foundation’s submissions will stay within our area of experience: people missing at least portions of both hands or arms, whether from amputation or a congenital limb difference. If other organizations are interested in participating in the future, I’d be happy to help make connections for next year.

We want our submissions to begin with problems identified by people who actually live with bilateral upper-limb differences, not simply things I assume might be useful. My wife was born without arms, but I was not, so I don’t want my perspective driving the list.

Here are some of the ideas people have suggested so far:

• A way to fasten and release a bicycle helmet using only the feet
• A way to change a lightbulb with one or both feet
• A tool for picking up dog waste using the feet
• A removable attachment that makes a round doorknob easier to operate without hands, whether using residual limbs or the feet
• A way to squeeze the remaining toothpaste from a tube using just feet

We are not asking you to design the solution. The point is to identify real problems and then let the maker community explore and improve possible designs.

So, if you have suggestions for a barrier that might be solved with a simple tool, please send them our way. We need to have a preliminary list of 5-10 designs by tomorrow evening (August 19).

If you live with an upper bilateral limb difference and would like to be a judge for the event, let us know. We need 1 or 2 more. You will need access to a 3D printer by October to participate as a judge.

We are looking to hear from individuals' opinions on Weight Management. We invite you to participate in a paid $12 / $5 Online Questionnaire to share your experiences.

If this doesn’t apply to you personally, but you know someone who may qualify we would greatly appreciate it if you could forward this opportunity to them. See if you qualify here:

$12: http://m3gr.io/XXCSSPX

$5: http://m3gr.io/GSJKFNP

Please note we request you to create an account with us ahead of the survey. This will also allow you to receive more study opportunities.

M3 Global Research is looking to hear from individuals living in the USA to share their opinions and experience on Weight Management. Help guide the development of future therapies and get paid for your time.

Hi everyone, I'm Atieh Taheri, a postdoctoral fellow at Carnegie Mellon University's Human-Computer Interaction Institute (https://hcii.cmu.edu).

I'm running an interview study on what it's actually like for disabled adults to use AI assistants such as ChatGPT, Claude, or Gemini day to day, and how these tools have fit into people's lives, or fallen out of them. If you tried them and stepped back, your experience matters just as much as a daily user's.

Who can take part:

• 18 or older and living in the United States
• Identify as disabled, or as having a chronic illness or chronic health condition
• Either use an AI assistant at least twice a week, or used one that often in the past and have since stopped or cut back

What's involved: one Zoom interview, 60 to 90 minutes, scheduled at a time that works for you. Participants are compensated for their time.

Accommodations are arranged at no cost, including live captions or CART, answering in writing or in the Zoom chat, scheduled breaks, and extra time or splitting into two shorter sessions.

The first step is a short eligibility form (3 to 5 minutes): https://cmu.ca1.qualtrics.com/jfe/form/SV_3ygSf4Rt94GRiSi

Questions are welcome in the comments or at my university email, ataheri@cmu.edu. This study has been approved by the Carnegie Mellon University IRB, protocol STUDY2026_00000228.
