100mm Estep calibration tool

This is 100mm calibration tool. I know it won't do you much good if you haven't gotten it close yet, but I can't fit my calipers in my enclosure very easily when they're set for 100mm, so I made this so I could check it easily or recalibrate easily if made a change. its exact dimensions rely on how calibrated your printer is. So get an accurate measurement after you print it and write it on the side so you can input that correctly. Mine came out to 100.6mm because my printer is a bit off in calibration.
