Single/Multi AA battery box/holder

Simply because there are often requests for some simple electronics from kids - like the one here - “hey daddy, this RC car friom grandma is awesome, but it does not have any lights:(” - and then I have to quickly figure out how to strap some batteries in and make it work:).

You can also “knock off” the little pins supporting the spring for printing in ca
