3D Printer Power Meter Case

prusaprinters

<p>This is a case for a Power Meter Module which measures:</p> <p>Voltage, Power, Current, Power-factor, Energy Usage and Frequency.</p> <p>It might be a good idea to add a fuse into the case, electrically before the Power Meter circuitry in case something goes wrong.</p> <p>The case is designed for the "20A" version which does not use a current transformer to measure current: <a href="https://www.aliexpress.com/item/20A-100A-AC-LCD-Digital-Panel-Power-Watt-Meter-Monitor-Voltage-KWh-Voltmeter-Ammeter-Tester-Tools/32934531215.html">https://www.aliexpress.com/item/20A-100A-AC-LCD-Digital-Panel-Power-Watt-Meter-Monitor-Voltage-KWh-Voltmeter-Ammeter-Tester-Tools/32934531215.html</a></p> <p>A KCD4 rocker switch is used to completely turn off the Power Meter and output: <a href="https://www.aliexpress.com/item/5pcs-2-Position-Red-Light-Rocker-Switch-16A-250V-KCD4-20-4-Pin-ON-OFF-Toggle/32815632983.html">https://www.aliexpress.com/item/5pcs-2-Position-Red-Light-Rocker-Switch-16A-250V-KCD4-20-4-Pin-ON-OFF-Toggle/32815632983.html</a></p> <p>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.</p> <p>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.</p> <p>You can adjust the model, I have included the Fusion 360 file.</p> <p>WARNING: MAINS VOLTAGE CAN BE LETHAL! I take no responsibility for any damages or injuries. Only qualified personnel should work with live (mains) circuits!</p> <h3>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"! :)</h3> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Tronxy X8</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div> <p><strong>Supports:</strong></p> <p>No</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>0.2mm and up</p></div> <p><strong>Infill:</strong></p> <p>100%</p> </p></p> Category: 3D Printing
