I was looking for a power supply cover since the day I bought this wonderful 3d printer, because I don't like the exposed contacts and the lack of a main power switch.
In the meantime I decided to add something to monitor power consumption when printing, because... well mainly for fun :D

At first I bought a DC power meter but since power in DC is well beyond 10A I had to buy a bulky DC power meter, and it won't never fit the tiny space under the power supply. Also, I was thinking about using all the three pairs of DC outputs so measuring that way is not possible.

I then found a cheap AC power meter from china that was perfect.. the only problem was that due to size it will not fit again under the power supply. The only solution was to design my own power supply cover.
I took inspiration (for an artist it means copying) from many other projects here on Thingiverse and I added mine as a remix of those. Thanks for your great work guys!

This is the cool 'n' cheap power meter I used, I paid about 7 dollars for it:

I also used an IEC socket with O\I lighted button, found at a local electronic fair but you can find on ebay easily.
In the next section I'll try to show you how to wire them up.

PLEASE NOTE: I have the first version of the Anet's power supply, marked 250w. I believe the 240w has the same size so it would be ok too, but probably not on the 180w version (if it exists).

Even if Simplify3D creates supports under the diagonal part under the display, in my many tries I discovered that this isn't really needed. The only support needed is the one on the left side, where the cable from the Z-axis motor will go through. You need to place supports manually there, at least with Simplify3D.
Look at the screnshot I uploaded to better understand.
