*Note: Added new top 18/10/2015 with hole to view 5V LED. This is the primary picture. Removed original top design.\nThis enclosure is for the DROK DC-DC Buck Voltage Converter 4.5-40V, converting variable input voltage from solar panels or car batteries down to stable 5V output supplied through a standard USB connection for phone charging.\nThe device can be purchased online through places like Amazon.com: http://www.amazon.com/gp/product/B00IWOPS8K\nThe cheap module allows use of variable input voltage and stops circuit shorting if installed in the car, with stress relief mechanism on the power cable.\nThere are four files:\n1) Bottom enclosure without mounting tabs\n2) Bottom enclosure with screw hole mounting tabs\n3) Top cover with simple buttons for main power on/off (LP) and 5V on/off (ON), plus LED hole for USB output power indication\n4) Top cover with no holes for always-on mode (minor circuit modification required)\nWhen printing with PLA, a push fit is sufficient to attach the top, but printed pins use the thicker inner diameter to prevent falling out. Craft knife cuts are necessary around outside holes before installation. Make sure buttons click on and off easily when gluing the top in place.\nThe two buttons work as follows: LP turns the unit and voltage display completely off, while ON activates the 5V output circuit. The surface-mount LED lights up through the USB hole. Cut some traces to disable these buttons if desired; more information is available from Amazon.\nPrint Settings:\nRafts: Not used\nSupports: Not required\nInfill: 10%\nNotes: Printed on a Monoprice 3D printer with black PLA at 220 degrees Celsius, using a glass build plate set to 40 degrees. Hairspray aids adhesion.
