Customizable Basic 18650 Tray/Holder

thingiverse

I wanted something simpler yet customizable, so I looked around for some holders that would fit my needs. I took note of a few different models out there, but none of them seemed quite right. When designing the battery holder, I used an 18.4 diameter for most standard batteries and an 18.6 diameter for one off-brand battery due to its unique wrapping. If you find that the holder doesn't fit your specific battery snugly, feel free to adjust the measurement as needed. To test the print without wasting too much material, try changing the row and column to 1. This will give you a quick print that's easy to check before scaling up to larger quantities.
