Small vault

This is small vault with 120 x 120 x 120 mm outer dimensions.

There is a holder for an ESP8266 (D1 mini) that drives a small servo (SG90) which moves the wiper. The wiper pushes a big bolt (M12, length appox. 47mm) up to lock the vault.

The door is held in place by two M10 bolts with a length of approx. 24mm.

Use a USB-connector with dimensions 15.2mm x 13.7mm in the left back to provide the ESP with power (and data).

After testing and connecting the ESP and the servo, place the divider wall to hide the ESP and cabling.

See photos for the end result and the components used.

The door handle and plug are optional, but make opening the door a bit easier.

Print in 0.3mm layer height and internal supports are needed for the vault part, but only for the ESP8266-compartment
