I only had four CR2450 rechargeable batteries and I liked the original design as the batteries do not touch each other. I am new to Fusion and all of this modeling stuff so I learned how to cut the STL into thirds and smooshed them together.
I tested each spot with a cell and also in one of my drawers, as seen in the photo.
I printed the one in the photo with a 0.6mm nozzle, Elegoo Gray PLA, with a 0.4mm layers.
Please be kind :)
The author remixed this model.
This version is a 2x1 for holding only 8 batteries.
