Magnetic Window Distancer with Cherub on a Leaf

# Window Distancer (with cherub)

A 3D-printed magnetic spacer for double windows. It keeps the inner and outer window
**60 mm apart** to prevent lever break the glass. A magnet pad sits against one window and the leg with a round knob rests against
the other. The decorative version carries a small cherub sitting on a leaf.

## Dimensions

| Parameter | Value | FreeCAD constraint (sketch) |
|---|---|---|
| Distance between windows (back of magnet pad → end of knob) | **60 mm** | WindowDistance (MainSide) |
| Height difference between the two windows | 5 mm | WindowsHeightDifference (MainSide) |
| Magnet pad height | 70 mm | MagneticPadHeight (MainSide) |
| Magnet pad width / thickness | 18 mm / 4 mm | Width (MagnetPadSketch) |
| Magnet pockets | 3 × Ø 11 mm, 1.5 mm deep | MagnetPocketDiameter (MagnetPocketSketch), Pocket length |
| Leg width | 6 mm | LegWidth (LegProfile) |
| Knob diameter | 25 mm | NobDiameter (MainSide) |
| Overall size (with cherub) | 60 × 33 × 88 mm | |

### Other window gaps
The model is parametric. To change the spacing for other windows:
1. Open WindowDistancer.FCStd in FreeCAD 1.1 or later.
2. In the MainSide sketch, change WindowDistance and WindowsHeightDifference, then recompute.

The cherub is a mesh, so it doesn't follow the change. After a big change, re-export the body
and re-fuse the cherub with the scripts in [tools/](tools/README.md).

## Versions (git branches)

- main: the plain distancer, without the cherub.
- angel: the distancer with the "Putto su foglia" cherub on a leaf. The leaf's underside is carved
  into a thin leaf with a midrib and veins.

Milestones are tagged, for example v3-1-legFilling and v3-6-angel-filletCove.

## Files

- WindowDistancer.FCStd: FreeCAD model, PartDesign body plus the cherub mesh.
- exports/WindowDistancer-angel.stl: the whole print as one fused solid.
- exports/WindowDistancer-angel-part1-distancer.stl, exports/WindowDistancer-angel-part2-cherub.stl:
  the same print as two parts, so the distancer and the cherub can get different print settings in the slicer.
- exports/*.3mf: OrcaSlicer projects for a Bambu Lab X1 Carbon.
- orca-presets/: OrcaSlicer process and filament presets for a smooth print.
  Import them with File → Import → Import Configs.
- tools/: Python scripts that place the cherub, carve the leaf and build the slicer project. See [tools/README.md](tools/README.md).

- scaled to 63 %, mirrored and tilted 40°
- the flat underside carved into a leaf with a midrib and veins
- fused with the distancer
