XL4015 enclosure (single, double, triple, quad)

thingiverse

XL4015 enclosureI'm using the cheap and widely available 'blue' XL4015 adjustable buck regulator in my robotics projects as they nominally handle up to 38v (but seem to tolerate 42v) and are passably efficient.This enclosure lets you mount 1-4 side by side, just print the relevant base. There is a countersunk hole for mounting the base to a flat surface and the covers are held in place with the kind of small self-tapping screws I'd expect most hobbyists to have kicking around.Print the base as is, but rotate the cover to print it 'top down' to reduce the amount of support material needed.Make sure you have the 'blue' boards shown in the photo and solder the in/out cabling though from the bottom of the PCB so it can pass out of the slot in the cover. Make sure you fit the heatsink so it fits inside the footprint of the PCB. There are holes in the top of the cover to allow heat to escape.Other variants of this common power supply board probably won't fit this model.I've used this to have 5v/12v/19v power supplies from a 10S nominal 36V battery.
