Relay Controller Case and Components

I was needing to house a relay controller solution I made using an ESP8266-12 module and later on an Oak by Digistump.
After looking around on Thingiverse, I decided to combine and remix a few already existing projects:

I used Blender to remodel the parts I needed, the electronics are just using a 5V power source and a 3.3 voltage regulator for the module, while connecting the GPIOs to the relay boards control pins. The relay boards are directly powered from the 5V power source as well.

The board base has imprints for the parts, the current version fits the ESP8266-12 module and depending on the printer, might need some filing to fit in place.
