No longer will you have to toil over your dress uniform or give up out of frustration. Like many others, I value my time and would rather spend it doing things I enjoy. That's why I created the Daltrometer®. Through precise 3D printing, you can quickly and effectively set up your dress uniform without second-guessing a measurement. By affixing rulers to a slider, measurements between 1/8" and 5/8" can be achieved by stacking rulers appropriately. Additionally, a right angle is created for offsetting awards and decorations. Using the Daltrometer® is as simple as: align, place, and press.
