Dimmer Mounting Box

I wanted to add a dimmer to control the LED lights in my Ikea Lack enclosure.

I purchased this:

I then wired it up to my 24v Prusa i3 MK3 power supply on one side and the 24v LED lights on the other.

I recreated the original design in Sketchup with bigger dimensions to accommodate the controller.
