LM2596 buck converter case

###### Description: A small case for the LM2596S-ADJ DC-DC buck converter. (With SMD capacitors I don't know the sizes of the version with through-hole capacitors, so those might not fit. Give me a yell if you have those, so I can make a version that fits those too!)

Two versions: both require different parts. The normal version is if you're putting it somewhere where the metal parts of the screw cannot cause any shorts (like outside a printer). The metal-less version is if you're putting it inside of the printer enclosure, and don't want any exposed metal which might cause havoc. (That's including the metal adjustment wheel!)

The case is meant for low power applications (like running a 12v fan on a 24v printer). There's basically no breathing holes, so not applicable for high power applications which actually require cooling.
