AD588BQ voltage reference module 2x15V battery compartment

I bought an AD588BQ voltage reference module from Aliexpress and realized that it needed two old type 15v batteries that was hard for me to find locally.

That is why I decided to create this battery compartment that allows me to use 5pcs of 3V CR2032 battieries for each 15V cell.

Other materials needed are m3 brass standoffs with a total length of 16mm. I used one 10mm and one 6mm brass standoff since that is what I had laying around.
