Battery Level Indicator tiny case

This is a tiny case that can house a mini Battery Level Indicator suited for 3.7v-4.2v 1s or 2s Lithium batteries with a mini push button next to it. I had bought 5xpieces on Aliexpress and I decided to integrate a piece into my Logitech joystick that I converted into a rechargeable device to check battery levels. To keep the battery level PCB and the mini push button together I first tried with superglue but that was a bad idea as everything is pretty tiny and you risk making a mess as it seeps everywhere (!) so better use a jelly-like glue that is more sticky and less liquid. Have a look at the pictures to get an idea of the wiring, the soldering points on the push button pins, and finished assembly.
