• TPU hardness selectorFree tool: pick your activity and get a starting TPU firmness (durometer + lattice density) and top-cover suggestion for a 3D-printed insole. No login. Design guidance, not medical advice.
• 3D Foot FitCompare a 3D foot scan with an insole STL, confirm the plantar surface, review alignment and coverage, and export a fitted STL. Free browser-based geometry QA for clinics and insole teams.
• STL Scale & CutResize, widen, and trim insole STL files in your browser. Split paired models, scale by size or millimetres, make a 3/4-length insole, and export printable STL files free.
• TPU printing guideHow to print TPU insoles: an example slicer profile for flexible TPU (95A, temperature, speed, gyroid infill) to check against your filament's data sheet, plus fixes for stringing and warping and top-cover tips.
• Detailed DIY print guideHow to make 3D printed insoles at home: capture fit inputs, generate an adjustable STL, slice for TPU, print on an FDM printer, then finish and wear-test.
