Simple frame for Arduino Nano breakout board and breadboard

The inexpensive and convenient 'Nano Expansion Prototype Board' provides Dupont headers for all pins of the Arduino Nano. Conveniently, all pins are flanged with 5-volt supply voltage, making it easy to connect sensors to the digital inputs via 3-pin servo wires. Servos can be connected directly to the PWM outputs through these triple-pin strips.

I made this enclosure for it, which can also directly house a small breadboard.

The Nano board is held in place with four simple pins which can optionally be melted flat for additional anchoring (which was not necessary in my case). The breadboard slides from below into the slots provided under the window. Four 17.5 mm felt pads can be sticked under the separate (optional) bottom plate.
