Pocket Voltmeter with Pass-Through port

thingiverse

I have an Esk8 that I didn't want to permanently mount a voltmeter in because space was tight and I didn't want to cut on the CF enclosure more than necessary. So, I came up with a Pocket Voltmeter with Pass-Through charging port. This allows you to plug into the charge port on your Esk8 (or whatever) and see the voltage plus you can then plug your charger into the pass-through port to monitor charging. This is what you need as far as parts. 5.5 x2.1mm DC Power Socket https://www.ebay.com/itm/111889160001?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT 5.5*2.1mm Male DC Pigtail https://www.ebay.com/itm/Lot-10x-5-5-2-1mm-Male-DC-Power-Plug-Connector-CCTV-PSU-Pigtail-CABLE-Jack-12V/272112575742?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 Voltmeter https://www.ebay.com/itm/LCD-12V-24V-36V-48V-Lead-Acid-Battery-Status-Voltage-Voltmeter-Monitor-Meter-Car/263889296209?hash=item3d71071b51:m:mBNt8R85So2EgKuA6m_LQ4Q:rk:1:pf:0 You solder the leads to the voltmeter to 2 wires, one side goes to the socket (pass-through charger port) and the other side goes to the pigtail (connects to the charge port of your Esk8). I forgot to take pictures of the internal wiring, but I'll do that on the next one I build and post those pictures. The model is slotted for M2 screws, but being such small holes and with the shrinkage inherent with 3D printed models, I had to drill them out. I ended up using epoxy to fix the socket and pigtail in place, plus some on the inside walls to keep the two pieces locked together. I used hot glue to secure the voltmeter in the top of the case. I may redesign this in the future to use M3 screws and a cap for the voltmeter. This would make it easy to disassemble, but will also make it significantly larger. Let me know if you're interested; I'll get it done.
