Power Meter Housing

thingiverse

I wanted a way to see how much power was being used and to make sure that my power supply was putting out enough power to make the printer run effectively. This is absolutely not needed, but I am a gauge-a-holic, so I wanted a dashboard for my ENDER 3. Bought the meter from AMAZON. IT is a 4 wire hook up and very easy to wire up. Made the harnesses, soldered and crimped connectors, added the shunt to the bottom of the power supply. I particularly like the fact that this meter calculates WATTS automatically. If I print this again, I plan on leaving off the "Power Meter" text. I am also going to print in PLA to see if I can get a better print quality. You could go for another type of meter, but this was what I had and it fits the space that I had available perfectly. Feel free to ask questions about this install. NOTE: I updated the STL file to version 2.2. This should print quicker, less materials used and look much better. I am printing a new control box as I type from this new file. Old box file is deleted. Finally was able to get one of the best prints that I have made. Just a very few flaws, but much nicer than all my others. The first two pictures are from the version 2.2, in PLA. Got rid of the ringing that plagued the other prints. Now I wish I had printed in a finer resolution, but that is for another day. Added a stand alone shunt mount that will slide into the rails of the machine, under the stock power supply. This mount can be placed on the side or the top of the rails.
