My son likes to design creations for me to print, but sometimes needs some help with what his "measurements" actually mean. I created this visualizer to let him see some basic sizes in millimeters.

This is version 1.0 of the model. The numbers on top are a little small and the 0.5mm bar is very fragile. But each bar is the size labeled, confirmed with my calipers. 

• 0.5 mm

• 1 mm

• 2 mm

• 5 mm

• 7.5 mm

• 10 mm

In the future, I may reconfigure it to be easier to read and less fragile.
