18650 50 Cell Battery Holder With Bus Bar Cut-out
thingiverse
I designed this battery holder for building my own 18650 battery packs and it turned out quite well. I made sure to leave space for a 1" copper bus bar and also reserved room for soldering connections between the batteries. This is actually my first custom design, but it's still a work in progress. It works fantastically though! 5-24-16: To make this holder even more versatile, I added hex cut-outs. At the same time, I thinned it down slightly to speed up printing. You can check out new pictures. 5-31-2016: I uploaded an additional STL file called 50_Cell_Very_Thin which has cut-outs that allow sliding brass center bus bars through along with extra hex bolt holes. Check out the pictures. It works great!
