Power Meter Housing

thingiverse

I needed to see how much power was being used and make sure my power supply was putting out enough to run the printer effectively. I'm a gauge-a-holic, so I wanted a dashboard for my Ender 3. The meter from Amazon is a 4-wire hookup and very easy to wire up. I made the harnesses, soldered and crimped connectors, added the shunt to the bottom of the power supply. This meter calculates watts automatically, which I like. If I print this again, I plan on leaving off the "Power Meter" text. I'm also going to try printing in PLA to see if I can get better print quality. You could go for another type of meter, but this was what I had and it fits perfectly. Feel free to ask questions about this install. The STL file is updated to version 2.2, which should print quicker, use less material, and look much better. I'm printing a new control box from this new file right now. The old box file is deleted. Finally, I got one of the best prints I've made, with just a few flaws but much nicer than all my others. The first two pictures are from version 2.2 in PLA, and I got rid of the ringing that plagued the other prints. Now I wish I had printed at a finer resolution, but that's for another day. I added a standalone 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 top of the rails.
