Airsoft M4 AEG stock spacer with volt meter

thingiverse

This is a stock spacer that I created that contains a .28 inch LED voltmeter and a micro pushbutton. It is wired in parallel with the battery wires. The housing is two pieces that are press fit. I included two front parts, one with a window cut out for the LED and another without. I printed this in a translucent orange and the voltmeter is visible through the plastic so no window is needed. Some soldering is involved. I just re-used the lead wires that came with the voltmeter. Make sure after soldering to wrap the back of the LED in kapton tape or some other tape so the micro push button switch doesn't short on the LED voltmeter pins. I killed two voltmeters before I figured out what happened. These are the other parts I used: - .28 inch led voltmeter: https://www.amazon.com/dp/B07Q2RQYPJ?psc=1&ref=ppx_yo2_dt_b_product_details - micro push button: https://www.amazon.com/gp/product/B01MRP025V/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 - kapton tape: https://www.amazon.com/gp/product/B07RZYY2T1/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 - wire (if needed): https://www.amazon.com/gp/product/B00B4ZQ3L0/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
