Buck Converter Case for 34x66mm PCB- Ender Rail mount

thingiverse

Used the rail from the "Ender 3 LM2596 with LED Case" by BradyZ and made a new box for my specific power board. If you have a PCB measuring 34mmx66mm and need to mount it to an Ender 3 (or any system with that rail style) then this may just work for you! I liked the standoff idea but the pins kept breaking off, so I converted to holes that I can mount through with small bolts. I vented the bottom for increased air flow, as I only have PLA and wanted to minimize any heat buildup potential. I left the directional indicators off as I wanted to mount it going the other way. I figured it may as well be universal, just pay attention when you actually wire it up! Lid is tight, file the corners slightly until it snaps in easily. I soldered the power leads inline on the printer side of the power supply, then adjusted the voltage to a stable 5.1 volts. Connected to my Raspberry Pi +5V and Ground GIPO leads, works perfectly and now powers up automatically with the printer.
