About the job
We need a library of clean, well-shaped 3D insole models in a range of sizes. The files will be used as base templates in an automated software pipeline. They must be tidy, consistent across sizes, and marked with key foot reference points.
We'll start with a paid pilot (one style, 3 sizes). If that goes well, the same freelancer continues with the full library.
What you'll create ?
Pilot (Milestone 1)
One full-length everyday insole design: realistic foot-shaped outline, moderate arch support, heel cup, edges that thin out to the border
Graded into 3 sizes: 240, 260 and 280 mm length
Left and right versions of each size
Full library (Milestones 2–3, after pilot approval)
The base style graded to 9 sizes: 220–300 mm in 10 mm steps (about EU 35–47), left and right
4 more styles based on the base design:
Sport: deeper heel cup, higher sidewalls
Slim dress: ¾ length, low profile
Boot: higher volume
Extra-cushioned: thicker, fuller contact
File requirements (every model)
STL, in mm, one solid closed body with no holes, overlaps or loose pieces
Flat bottom sitting on the XY plane (z = 0)
Fixed orientation: heel at x = 0, toe toward +x, top surface facing +z
Consistent triangle density (roughly 20k–60k vertices)
Native source files as well (Rhino, Grasshopper, Fusion 360, SolidWorks or similar), ideally a parametric model so sizes can be regenerated
Annotations (every model)
We'll give you a simple spreadsheet or JSON template to fill in with x, y, z coordinates:
Points: heel centre, 1st and 5th metatarsal heads, arch apex, navicular point, lateral arch point, big-toe tip, little-toe tip
Lines (as point lists): heel-cup rim, inner and outer sidewall top edges, forefoot trim line
Zones (as outlines): heel pad, arch, metatarsal area, toes
You don't need medical knowledge. A short reference sheet shows where each point goes.
Skills we're looking for
Strong freeform surfacing (Rhino, Fusion 360, SolidWorks or similar)
Experience with footwear, insoles, lasts or other body-fitting products (strongly preferred)
Size grading and parametric modelling
Clean, printable meshes (3D-printing experience a plus)
Timeline and budget
Pilot: about 25–30 hours, done within 2 weeks
Full library: about 90–110 more hours, over about 4-5 weeks
Hourly or fixed price per milestone. Please quote both phases.
To apply, please include
2–3 examples of footwear, insole or other ergonomic surface work
The software you'd use, and whether you'd build it parametrically
Your estimate and price for the pilot
One sentence on how you'd grade one design across 9 sizes and keep it consistent
All designs and source files become our property. An NDA is required before starting.
