Rechargeable battery case

myminifactory

This rechargeable battery holder is exactly what you need when you're like me and have an abundance of rechargeable batteries, but get frustrated with them constantly falling off the shelf due to their size. Its design specifically caters to 18650, AA, and RCR123a batteries, but can easily be scaled up for any other size battery type. I printed it using ABS plastic, which causes thermal expansion that slightly tightens its fit on the batteries. To accommodate this issue, you might want to increase the scale by about 5% if using ABS or PC plastic. You may not need to make this adjustment if using PLA or PET plastic.
