3D Printer Power Meter Case

thingiverse

This is a case for a Power Meter Module that measures Voltage, Power, Current, Power-factor, Energy Usage, and Frequency. Adding a fuse into the case, electrically before the Power Meter circuitry, might be a good idea in case something goes wrong. The case is designed for the "20A" version which doesn't 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 or screw down the angled stands of the case. Unfortunately, the LCD used in the Power Meter doesn't have great viewing angles, especially when looking from a high angle, the LCD becomes unreadable. You might 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 couldn't read the display with the case mounted on my printer's desk when I was standing right in front of it. I raised 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"!
