Update2: Enlarged 10 battery version in X, Y and Z to accept 21700 batteries
Extra info:
The models are meant to be used with flat tops.
If you want to use these for button top batteries, please be aware of the inside width:
18650 model: 68,8 mm
26650 model: 68,8 mm
21700 model: 73,6 mm
If you want to use these for button tops, check if the total length of your battery is less than the numbers above (careful not to short the battery when measuring).
If not you can adjust the scale in your slicer a bit bigger:
18650/26650: Scale factor = (length of your battery)/65
21700: Scale factor = (length of your battery)/70
