The Controller Project is a volunteer initiative that develops modifications for game controllers that allow the physically disabled to use them. Participants can donate money, design skills or 3D printing skills to the cause, which allows them to distribute free 3D-printed game controller add-ons to disabled gamers.

TCP has a champion in Akaki Kuumeri, the natural-born industrial designer we looked at here. Kuumeri has used both his design skills and his mastery of 3D-printed flexures to create a non-destructive add-on for the PlayStation 4 controller that allows the user to wield all of the controls one-handedly.

Kuumeri's design is pure form-follows-function and incredibly clever besides, incorporating several outside-of-the-box solutions for manipulating controls that outnumber the fingers of one hand:

I was particularly impressed at how he handled the challenges of designing for a right-handed add-on versus a left-handed one.

Kuumeri sells the add-ons on his Etsy page; but as per The Control Project's open-source model, he's also made the .stl files available for free downloading at the Prusa Printers website, and gamers can request a free unit from The Controller Project.

If you have a project from last year that you’re proud of then take a few minutes to send it in to the 2022 Core77 Design Awards. We have 18 categories of practice, and for this year we have a special Sustainability Prize for any projects that have a beneficial environmental impact. Check out for details and schedules.

I’m a lapsed industrial designer. I was born in NYC and figured I’d die there, but a few years ago I abandoned New York to live on a farm in the countryside with my wife. We have six dogs.
