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
