LM2596 enclosure, vented with 20mm fan, for buck converter

My LM2596 boards use standard electrolytic capacitors, which are subsequently taller than the solid caps on other varieties.  I tried a few different models, but they were all a little too short for my boards to fit.  This model on Cults was tall enough, and vented.  It also is set up for a 20mm fan, which I had on hand.

It was embossed, so I used MS 3D Builder to block out the text, and I put a little cylinder in the hole to fill it in, since I didn't need a power button.
