When my 2016 X-carve controller board stopped working I looked for alternatives, I opted for the Arduino shield designed by Nikodem Bartnik. https://indystry.cc/product/indyshield-cnc-arduino-shield/

with my CAD skills, I designed a box to hold all of the components I was going to use. 

1. Arduino & shield
2. TB6600 drivers
3. Power supply
4. plug/ switch 
5. two salvaged fans
6. Aviation plugs

Here is what I came up with.
