# Parametric Box
This FreeCad project generates a box with a sliding lid and finger-shaped interlocking joints.
It is designed to be manufactured on a CNC mill.

The following parameters can be set in the spreadsheet:
- height (outer dimension)
- width (outer dimension)
- depth (outer dimension)
- finger width
- clearance for glued parts
- clearance for sliding lid
- slot depth in relation to material thickness
- material thickness (sides)
- material thickness (bottom)
- material thickness (top)
#### Example for a very flat box
*notice*: The height and the finger width must be choosen in a way that at least three fingers can fit on a corner edge

### TechDraw
The project includes a TechDraw page, which can be used for CNC-milling when exported as `.dxf`.
All Views are updated and placed automaticly, when parameters are changed. Spacing can be adjusted in the Spreadsheet
