Buck converter case, HW-384

Snap together case for HW-384 buck converter.  I prefer PETG because I had problems with PLA tabs snapping off when putting the top on.  There are standoffs on the base for wire clearance and ridges in the walls to snap the PCB into.  I use these to put buck converters in automobiles where a bare board may contact metal and short.  They give me a base to use VHB tape to hold them in place without worrying and are still attractive enough if left visible.  I don't put a significant load on the ones I use, so heat isn't an issue for my application, but these are rated for 3A, so your mileage may vary.
