18650 Battery Size Gauge

All 18650 batteries are not created equal. All filament materials as well as printers and slicers do not print the same. Before I started working on a cell holder I wanted a method to accurate determine the required hole size for a particular brand cell, material and printer. I measured several 18650 cells I had on had and came up with diameters ranging from 18.05 to 18.30 mm in diameter. So the gauge I came up with has hole sizes from 18.00 to 18.50 mm in diameter in 0.05 mm increments.
