ShoeForm is a measurement-driven tool for generating custom 3D-printable shoe lasts, purpose-built for small shoemaking workshops. Instead of adding cork to stock lasts by hand, an instructor enters five standard foot measurements per student, selects a template last, and ShoeForm modifies the template in under a second to match those measurements, using radial basis function interpolation for smooth, natural results.
The app manages students and class cohorts, lets you fine-tune fit with ease parameters, previews the modified last in an interactive 3D viewer with cross-section comparisons, and exports to STL or 3MF for overnight printing. It turns a full day of manual last modification into a few minutes of data entry.
I run a shoemaking workshop on Salt Spring Island through the Wilding Foundation. The tools for this kind of work are too expensive for our little operation. So I built my own.
