C and D Battery Storage Box

I have tried a couple of versions of battery holders and I didn't really need a dispenser I just needed something to keep things from rolling around in the drawer. I found this design https://www.thingiverse.com/thing:2876022 and I really liked how well it worked out for me so I designed a C and D to accompany it.

D Holder fits 10 total batteries - 5 per row
C Holder fits 6 per row and I think you can get 3 rows in there, haven't filled it all the way so I am not sure but I am guessing 18 total.

I used the same wall thickness as the print I mentioned above at 2mm to make it look similar.
