Kossel Mini Power Switch with Voltmeter Plate

thingiverse

I'm adding a small three-digit LED voltmeter next to my KM power switch, and as luck would have it, they fit perfectly snug between the base's extrusions! This plate securely fastens down in the corners and accommodates a standard 12x27mm switch plus a basic Chinese three-digit LED voltmeter from eBay like this one http://www.ebay.com/itm/141049350659?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT. A small indentation on the back side provides a perfect fit for the voltmeter; I secured it with a couple of superglue dots, but honestly you might not need them since it's a very tight fit. Then simply wire the voltmeter to the power after the switch so it turns on along with the rest of your electronics and acts as a power light too! I plan to create something similar for my heated bed circuit's AUX power input soon, using a red voltmeter; stay tuned. Print with a clear filament such as ABS, PLA or PET for optimal results. I used clear PLA and even with 1mm of solid infill, the digits are still sharp and very bright. You will need 4 screws that measure 3x5mm and 4 nuts in the base extrusions.
