Some time ago I illustrated by simple "project box" for the LM2596 Buck Converter. Some might recall that I use a length of 20mm PVC Pipe with end-caps to host the converter. Now this works well but does not look that professional. I decided to print a 3D Printer Project Box as depicted in the images underneath. Recognition to FEDORSOSNIN for the design of the Box and STL files available HERE.
"A tool-less, snap-fit enclosure for your LM2596 buck/step-down converter that should snap-onto any 2020 extrusion without extra hardware. This enclosure also allows you to keep your wires separate via the outside channels or together in one via the center channel."
