This is a simple battery holder for a battery pack. 3S = 3 batteries in series giving 12v, 6P = 6 batteries in parallel, increasing the storage capacity. If the battery box could hold more I would've gone with an 8P.
I'm converting my 12v 11Ah lead acid battery to lithium ion battery pack for my motorcycle.
I have seen a few of these on here but the 2P strips don't fit on them so I quickly through this together. I found those strips to be quicker when assembling the battery pack.
I think the hardest part is designing it to fit different 18650 batteries. 18650 stands for 18mm diameter and 650mm length. I quickly realized these measurements are loosely followed by different manufacturers.
I printed these in ASA. ABS would be about the same. I'm not sure how hot the battery pack will get so I didn't want to use PLLA, or even PETG, in case it melts or distorts the holder when in use. I'm sure those will be ok to use but I didn't want to take the chance. Especially since it'll be sealed and I won't be able to gain access to it after the case is put back together.
I've included the .blend file.
Here's the video I followed for making the battery pack.
