A 60 × 40 × 25 mm inside box with 2 mm walls and floor, a 4 mm corner radius and a 4 mm lip is 64 × 44 × 27 mm outside; the usable capacity is 60 × 40 × 25 = 60 cm³ and the lid adds 6 mm of stack height (2 mm plate plus a 4 mm lip).Open the 3D-Printable Box with Lid Generator

What is the 3D-Printable Box with Lid Generator?
Enter the inside width, depth and height you need — for a circuit board, a set of dice, a gift or a spare-parts tray — and this generator builds a rounded-corner box and a matching lid with an inner lip that holds it by friction. You set the wall, floor and lid thickness, the corner radius, the lip height and the fit clearance per side, and the tool shows the outside size, the volume of plastic, the filament needed and whether both parts are closed solids.
The box prints open side up and the lid prints plate-down with the lip upward, so both lie flat on the bed with no supports. Download the box and lid separately or together on one plate laid out side by side. Because everything is generated from your numbers, it is easy to iterate: print a quick test, adjust the clearance by 0.05 mm, and print again.
