I designed this to carry 15 18650 batteries. The battery divider is removable. It is a remix of 
[https://www.thingiverse.com/thing:4757317.](https://www.thingiverse.com/thing:4757317.) I re-designed the hinge and latch, made it thicker and to use M3 bolt. I used the latch from [https://www.thingiverse.com/thing:4582978.](https://www.thingiverse.com/thing:4582978.)

I printed in .4 nozzle. Slice the hinge part and the latch mounting to 100% infill or increase the wall count to make it solid. Print the divider minimum of 2 walls no infill.

It needs a little bit of sanding on the hinges. You will need M3x20 and M3x30 2 each, nut is optional.

*Uploaded Fusion 360 file for those who want to remix it. The file is a bit messy as i am a newbie on Fusion 360.
