This is based on https://www.thingiverse.com/thing:2165589 by Tapion This is a simplified design of the above mentioned battery case. What this does is allow you to print 2 of this object. Both pieces can be used as tops or bottoms. I left an approx. 1mm gap so i can tell if batteries are inside before picking it up. You can also just print one off, and use it so your batteries aren't rolling around. Its a good idea to sand a little bit inside the so your material is not scratching your battery casing, but that depends on how good your printer can print. I have only printed this in PLA, but I don't see why ABS wouldn't work.
