500W CNC spindle control box

Enclosure to hold control electronics for a 500W brushless spindle, including the on/off switch, speed control potentiometer and speed display.

The bottom of the enclosure is empty as it is to be mounted to a wooden base.
The power wires then enter from underneath.

I have not included any vents for airflow. I want to keep dust off the electronics if possible. The controller stays cool in operation when run open on the bench. I will keep an eye on the internal temperature and add a fan in the future if required.
