dc to dc buck converter box usb charger

thingiverse

I crafted this compact enclosure specifically for housing a dc to dc converter that I purchased on Ebay. The device features an identifying mark on the rear labeled XY-3606, yet I've observed similar products available on Ebay and Amazon with varying letter combinations preceding the 3606 designation. Furthermore, they may be exhibiting diminishing availability. My search query was "dc usb buck 5A," which yielded a diverse assortment of converters, including some that should have been included in the search results. The enclosure measures 63mm x 27mm in dimensions. This device is designed to convert a 12-24vdc input into a 5vdc output at a rate of 5 amps. It boasts terminal blocks at both ends and incorporates a standard 12vdc connector for input, as well as a usb port for output. I utilize this setup to charge my Samsung tablet while on the go in my truck, utilizing Verizon's network and relying on Waze and Google Maps for navigation. The digital display, measuring 23mm x 10mm in size, features a compact design. The board itself measures 23mm without the ears and 33mm with them, along with a width of 11mm. I successfully connected it to the terminal blocks adjacent to the usb port. To prevent potential obstructions within the enclosure, I applied a strip of black tape across the rear of the led display. The hole in the lid designed for this display is quite snug-fitting, requiring careful scraping along its edges with a razor blade to ensure a secure fit. A very tight press fit holds it in place, and if you push too far, you may need to apply a small amount of super glue to maintain its position. The square opening on the enclosure is reserved for the usb port, accompanied by a temporary support in the center for simplified bridging during printing. It's recommended to remove this support post-printing. The lid snaps onto the enclosure with considerable force, especially during the initial few attempts. I began placing the end of the lid at the center of the box and then slid it downward before snapping the other end into place. After 3-4 repetitions, the connection loosens slightly. I fabricated this design using black abs, employing a layer height of .2mm and an infill density of 25%.
