Mount your LM2596 Step Down Module on Mini Kossel
Since I am installing Raspberry Pi for run Octoprint , so I use LM2596 for step down DC 12V to 5V and supply power to Raspberry Pi.
Many LM2596 on ebay didn't have current meter , but I found this with output current display.
I design two case , one have M3 screw hole for mount on Mini Kossel.
One case without screw hole.
LM2596 with Voltmeter and Current Meter
For the case , you need M3 x 10mm screw x4 , M3 Nuts x 4
