While planning out the Octoprint pi, camera, and power mounts for a Ender 3, I realized I had a different DC-DC Buck Converter on hand i.e. the XL4015 DC-DC Buck Converter. Rather than pick up new power converters at Toshi Station (wink wink), I remixed the LM2596S Mount from https://www.thingiverse.com/thing:2889371 and expanded the dimensions to work with my XL4015's.
Also, I removed the holes: The XL4015 I have only has two holes for screws and having 2 screws protrude from the bottom would be wobbly. I plan to just hotglue the converter into the case.
With this converter, I can use a XT60 splitter cable to get 24v from the power supply, convert it to 5v, and power the Pi without external power sources.
Hey, this is my first remix!
PLEASE NOTE: PLA is an iffy material to use for things that deal with regulating or transforming power (heat is an issue with these types of components). Be mindful of the temperatures of your electronics. I haven't tried it but ABS or PETG might be a better choice.
