This model is a simple but well-designed press-fit box, consisting of:

Press-fit box with snap lid in two depths: 100×100×100 mm and small 100×100×50 mm.

Box inner size: 95 × 95 mm

Lid lip (outer size): 94.8 mm → 0.2 mm clearance fit

Chamfer (bevel): 0.3 mm at 45° on the inside edge of the box + top edge of the lid lip

Designed in: FreeCAD (Part Design), fully parametric

Two separate bodies: Box + Lid

Why does it fit so well?
The combination of the 0.2 mm tolerance and small 0.3 mm chamfer ensures the lid slides in smoothly and holds firmly by friction. No wobble, no resistance, no tools needed.
