I MOVED TO PRUSAPRINTERS.ORG, PLEASE VISIT MY PROFILE THERE AND DOWNLOAD THERE! THANKS!

https://www.prusaprinters.org/social/229741-wizeus/about This is a case for a Power Meter Module which measures: Voltage, Power, Current, Power-factor, Energy Usage and Frequency. It might be a good idea to add a fuse into the case, electrically before the Power Meter circuitry in case something goes wrong. The case is designed for the "20A" version which does not use a current transformer to measure current: https://www.aliexpress.com/item/20A-100A-AC-LCD-Digital-Panel-Power-Watt-Meter-Monitor-Voltage-KWh-Voltmeter-Ammeter-Tester-Tools/32934531215.html A KCD4 rocker switch is used to completely turn off the Power Meter and output: https://www.aliexpress.com/item/5pcs-2-Position-Red-Light-Rocker-Switch-16A-250V-KCD4-20-4-Pin-ON-OFF-Toggle/32815632983.html The additional mounting pieces can be used to clamp / screw down the angled stands of the case. Unfortunately the LCD used in the Power Meter does not have great viewing-angles, especially when looking from a high angle the LCD becomes unreadable. You might able to see it on my picture that I didn't choose a steep enough angle for the triangles under the main case. This meant that I could not read the display with the case mounted on my printer's desk when I was standing right in front of it. I rose the front of the case with two screws. You can adjust the model, I have included the Fusion 360 file. WARNING: MAINS VOLTAGE CAN BE LETHAL! I take no responsibility for any damages or injuries. Only qualified personnel should work with live (mains) circuits!

If you build this project and want to give me something back in return, I'd be extremely happy to see a post under "Makes"! :)
