Ergono3D, a healthcare MCP platform, is a browser-based custom insole design generator. By replacing technical CAD work with simple inputs like use case and foot parameters, users simply select their use case and enter basic foot measurements—no CAD or manual modeling required. Makers, athletes, and clinicians can generate parametric designs and export 3D-print-ready STL files in minutes on Ergono3d.com

Maker
📌
We built Ergono3D because making custom insoles shouldn’t require CAD skills, or expensive software. Millions of people deal with foot pain every day—standing long hours, running, lifting, or simply wearing shoes that don’t fit quite right. The solution has always existed, but it was locked behind professional modeling tools or $150–$300 clinical services. We wanted to break that barrier. Our engine is backed by world-class biomechanists and design experts who’ve worked with top athletes and clinics, and we’ve distilled that knowledge into a tool anyone can use. Ergono3D turns a few simple inputs—use case, arch profile, posting preference—into a 3D-printable insole STL in minutes. No CAD, no manual modeling, no guesswork. We spent years refining parametric geometry and testing real TPU prints so that everyday makers, athletes, and clinics could design, iterate, and reprint until the fit truly feels right. This is our first step. We’ll keep evolving the engine with more foot types, sports modes, and parametric controls—so anyone with a printer can make insoles that actually work for their body.

This is such a killer use case for 3D printing. 🚀

I’ve actually tried modeling my own orthotics before, and honestly, getting those organic curves right in CAD without professional tools is a total nightmare. It’s crazy that until now the options were basically 'cheap drugstore foam' or 'pay a specialist $400.'

Really curious about the posting preference you mentioned—is the engine actually adjusting the internal lattice density to create that support, or is it mostly just changing the external geometry?

Also, for the print itself, is the algorithm tuned for standard 95A TPU? I'd love to know if I can get away with stiffer/softer filaments and still get the right biomechanical response.

Super excited to test this out. The ability to print, wear it for a day, and then tweak the fit for just $2 of filament is a huge unlock.

As a heavy guy with flat feet I have crushed every insole I tried to print myself. Standard gyroids just collapse under 200lbs unless I spend hours tweaking density settings.

Does your algorithm account for user weight to automatically reinforce the lattice? If you solved the physics so I do not have to manually engineer the durability that is a huge value add.
