Small enclosure for the 4x4 Matrix Keypad.

The case is 78 mm wide and 77 mm long. The total height of the case is 21.5 mm where the bottom is 20 mm. Hole for wires at the bottom, being 10 x 20 mm.

Lid is snap fit, so you it can be a bit hard to take off ones first assembled.

Unlike my other keypad model this only rests on the four pins. I had some trouble getting reliable printing due to how thin the pins would have needed to be. The slot in the lid and pressure from the pins helps keep the keypad in place when the lid is snapped on. 

Printing instructions:

Print the lid with the top down and the bottom with the bottom down. Supports might be needed for the hole on the bottom side of the case depending on the printer.

The model in the picture is printed on a Bambu P1S with:

• Filament: Bambu PLA Basic
• Infill: 15%, Gyroid
• Supports: No
• Adhesion: No
