Universal Wemos D1 Box

Like a lot of things, the idea for this box came from my own frustration of creating a new box for every ESP8266 project.
I decided to create a small case that satified each of my needs.

The result is a case, that can house a LM2596 DC DC converter, a 18650 battery or a Hi-Link module for use as power supply.

The Wemos D1 is in a separate compartment and any Wemos shield (or other sensor) in a third compartment. This compartment can be closed with a small plate, that you can slide into place. This plate can be customized to fit a sensor, pushbutton, just slits for an internal sensor, wires (like in the photo for a relay shield) or ...
This is the only part I have to design for a new project.

For use with the 18650 battery I use a Wemos battery shield, that can be soldered piggyback on de Wemos D1. There is no room for connectors, so I use a little spacer between the two components. This prevents the two from touching and it takes the battery shield at the correct height for
