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.
A base without the clips is included as well if you would rather use double sided tape or need to attach it in a different way.
Enjoy and post your makes!

Update 5: I have added v2 of both bases. This fixes the accidental gap in between layers causing weakness of the mount that holds the board. Should be all good now.
Update 4: I have printed 3 sets of these with the updated tabs. With my recommended settings below, they are much stronger. I have uploaded new photos.
Update 3: After printing 4 copies of these, they REQUIRE a high infill %. I suggest at least 80%, slow it down to 40mm/s, and do a .1 or .15 layer height. Otherwise, the tabs are hollow and snap off with ease.
Update 2: Please use "Lid-v2.stl" as I have updated the tabs to be stronger. I would also suggust printing at .1 or .15 layer height for added strength.
Update 1: The tabs on the lid are a bit too small. They are fragile. I will upload a v2 shortly with better, stronger tabs.
Thanks to @enkoopa for the snap on lid idea and @Andys1957 for the converter mounting idea!
