Repetitive motion injuries are no joke, often attended by crippling pain and the possibility of expensive surgery with a lengthy recovery. Early detection and treatment is the key, and for many wrist and hand injuries such as [ktchn_creations] case of “Blackberry thumb,” that includes immobilization with a rigid brace.

Sadly, the fiberglass brace her doctor left her with was somewhat lacking in the style department, and rather than being left with something unappealing to wear for half a year, she 3D-printed a stylish and functional wrist immobilizer. Starting in Autocad, she designed the outline of the brace, essentially an unwrapped version of the splint she started with. For breathability as well as aesthetics, a pattern of tessellated hexagons was used. The drawing was then exported to Fusion 360 for modeling and printing in black PLA. We were surprised to see that the brace was printed flat and later heat formed around her wrist, but that makes more sense than printing it in its final wrapped state. With a few velcro straps, the thermoformed brace was ready for service on the long road to recovery.

While [ktchn_creations] stipulates that looks were the motivator here, we’re not unaware that a 3D-printed brace might be more affordable than something dispensed by a doctor. But if you do build your own DIY appliance, whether for bracing your wrist, your knee, or your wayward teeth, you’ll want to run it past your health care provider, of course.
