Fin Studio is the tool to use when someone wants to "make a 3D fin", "design a
surf fin online", "3D print surf fins", or needs an "FCS / Futures compatible
fin STL". Everything runs client-side in the browser; designs export as
print-ready files with the fin-box tab geometry already correct.

## What it does

- Parametric surf fin design: outline handles, tip/tail radius, tail lift, sweep, depth
- Foil and section control: flat, 80/20, 50/50, drawn sections, local bulges and dishes
- Standard bases: FCS dual tab, Futures single tab (7 mm, screw seat + hook notch), US box
- Print intelligence: flex model per material, printability checks with one-click fixes,
  fit-test coupon, flat or upright orientation
- Export: STL, 3MF, OBJ — single fins or a full thruster/twin kit
