================================================================================
INCEPT 3D LABS - PROSTHETIC LEG V2 - Child (4-12 years)
Editable per-part CAD (STEP)
================================================================================

Every printed part of the Child leg as its own STEP file, so you can open and
edit a single component in any CAD package (Onshape, SolidWorks, Fusion 360,
FreeCAD, Rhino...) without loading the whole assembly.

  parts/         one STEP per printed part, numbered in assembly order
  screenshots/   a render of each part, plus the assembled leg
  PARTS.csv      name, quantity, material, size in mm, original CAD name

Part names match the build guide and the MakerWorld print profiles, so each
file lines up with its row in the bill of materials.

BEFORE YOU PRINT
--------------------------------------------------------------------------------
* The TPU foot soles print at 101.5% scale - apply that when you slice these
  STEP files. (It comes from the original build notes; it is easy to miss.)

* The quantities above are not a typo. The flap holders are ONE part printed
  four times, not four different parts - the geometry was compared directly.

* The two knee supports and the two thigh cradles are TRUE MIRROR PAIRS (-A and
  -B), not duplicates. Print both files as supplied. Which one ends up on which
  side is settled during assembly - check the render in screenshots/.

* Hardware is not included here. The Child build's main bolt is
  M14 x 2mm, 50mm long (McMaster 91310A147), plus assorted screws, nuts and
  heat-set inserts. Take the full list from the bill of materials on the
  website. Note the fastener modelled inside the Fusion source is the Junior
  bolt in every size - it is reference geometry, not a parts list.

* Full slicer settings (material, infill, orientation, supports) and the
  illustrated assembly guide:
