Enclosure for 7-28v to USB 5v Step Down Converter

thingiverse

A speedy enclosure is needed to house a 7-28v to 5v USB 1.5A step down converter, and a 5.5/2.1mm DC socket. Print both halves, wire up, and test the converter and DC jack (I added an extra capacitor on the output to keep one of my devices running smoothly), apply 5-minute epoxy to the top/bottom of the USB connector, around the DC jack, and on the edges of the enclosure, clamp it all together and wait for it to cure. Inserting a USB plug the first time is a bit stiff, probably should have put some tape across the holes to prevent any epoxy from getting in, but it works fine once you've inserted/removed a couple times. Note: It's likely a good idea with these converters to apply power before plugging in your USB device, in case of any spike while the converter stabilizes.
