This is the newest version of the ScanBand series of arm-measuring devices. This time around, I've made it as narrow as I think it can possibly get. The measuring numbers were turned 90 degrees and laid out side-by-side along the edge. The bar codes are the same size as version 0.4, but I think this is as small as I can make them while still allowing for them to be scanned.
