And orthotics among other prints.
Who designs the orthotis that you print?
Thingiverse 
I think they have to be designed for the person, no?
I was joking about Thingiverse.
Ideally, yes, orthotics are designed for each individual. However, many people have very similar foot issues, so an orthotic made for one of them will often work for many of the others. That’s how the Dr. Scholl’s orthotic display works. You stand on a sensor plate in your sock feet and it measures the pressure points on the bottom of your feet. It then recommends a numbered orthotic that will help even out the pressure on your feet. I’m sure it’s not completely perfect, but I suspect it’s a big improvement for many people, and for a lot less money than a custom orthotic.
As an example, about a decade ago I had Plantar Fasciitis. It was pretty painful. Each morning I had to walk about 1/8 of a mile to work out the cramping and be able to walk more or less normally. I read up about it online and found a forum where a guy said he cured his PF by getting a pair of Merrell runners with their Vibram sole. I tried it. In 2 weeks my PF was gone. Since then I have stuck to Merrell shoes and my PF has never returned. So, a generic ‘orthotic’ worked perfectly for me. In fact, one day we were in a shoe store with a Dr. Scholl’s display, so I tried it. My feet had such even pressure all over that I didn’t need any orthotic; confirmation of the benefit of the Vibram sole.
I design every orthotic device according patient needs. Every orthotic is custom made. Besides Mech Engineer i’m Orthotist engineer too!
Well, that works out conveniently for you… 
Yes and no! You were lucky enough to get help from a generic " orthotic" that other people get worse and even worse by them ( and this is not because those generic are not perfect, but they are not covering every deformation ). Only a Foot specialist can guide a patient on what to wear.
When i design a Spine brace, the deformities i’ve been called to correct are many. An orthotic engineer called to correct many strange and at the same time dengerous deformities in a way the will help doctors to complete their job on the patient easily. Combining technologies is my forte and this is why i choose to design and build my machines.
I was not trying to downplay the importance of custom orthotics. Actually, I don’t think Dr. Scholl’s would either. To me, the idea of the Dr. Scholl’s displays is to give people an option that’s priced between doing nothing and paying hundreds, or thousands, of dollars. For many people, one of the Dr. Scholl’s options will work fine. It’s not an expensive option to try. If it doesn’t work and things either remain the same or start to get worse, they can, and should, go to an orthotic specialist. I’m sure you have no shortage of patients.
That is impressive.
Spine braces are a whole different category. Trust me, there is no Dr. Scholl’s Spine Brace display, nor should there be. Spines are way too sensitive, and intricate for some generic solution.
Of course you did’t try to downplay Custom orthotics. Actually in Dr. Scholl’s labs are working orthotist scientist as well. There is no shortage of patents at all my friend. I’ve offered custom devices for free because of poorness of the patients. We are humans and we must serve humans as well!
Braces are also orthotics as well!
It’s wonderful that you help the less fortunate like that. Good on you.
I once saw a documentary about a mountain tribe in South America where the people pretty much all live to be 90, and many live to be over 100. In that tribe the elderly are expected to contribute to the collective, so no one feels unneeded or isolated. I bring this up because they showed a guy who makes mud bricks to build the houses and other buildings in the village. He pours water into a shallow depression in the mud and then walks around in it until it becomes thick like cement. His feet were the most misshapen I have ever seen on a human being. All the years of "mud stomping’ had distorted the bones and ligaments to the point that no orthotics on Earth would fit him. Of course, he never wore shoes either.
In this case, the whole body structure follows his feet. Feet are body’s base and the brain collaborates with feets. Even feets is under evolution while the human is growing up and so!
I can’t say as how his body was particularly odd. Put it this way: I didn’t see anything in his body that really stood out as odd, or made me think his feet had affected his body. He was skinny, but so was everyone in the village.
You can’t just see it, because you’re not a specialist!
It’s like when i design artifical joints for special needs! I must see his X rays or the have his 3D bone scanns
Fair enough. I’m just saying there was nothing obvious. He formed bricks just fine, and carried them in his arms without issue, and his back looked normal.
