This is a parametric customizable box that I designed in OpenSCAD to allow me create enclosures mainly for PCBs and small object, with a screwless lid that simply clacks in place.

Customizable features:

• Create box, lid or both
• Dimensions
• Wall thickness
• Corner radius
• Lid thickness
• Lid ledge depth
• Lid lip tolerance
• Holes can be enabled independently on lid, sides and bottom, with separated border offsets
• Hole diameter
• Hole separation
• Alternating hole patterns

Can be used also as a library for other designs (as I did for my Sonoff R3 minimal enclosure).
