By default the 18650 design is too loose for all of my Li-Ion cells (even with ABS shrinkage) although they fit LiFePO4 fine.

I made some more with clearance = 0; and they are a little tight but fit pretty much everything, so I assume clearance = 0.1; would be perfect.

With the differences in printer output and variations in battery casings between manufacturers, I'm definitely not surprised some adjustments are needed there for some at the tenth of a millimeter. I'm glad you got it working for you! I'll consider that a successful point for parametric design.

haha yes, i rarely download (or upload) anything not parametric. thanks for the design!

I love it! I always toss at least a couple 18650 batteries in my bookbag every day, and have worried in the past about the rechargeable AA and AAA cells I have rolling around in a drawer in my toolbox at work. Gonna print a few very soon!
