This is a bridging test. There are 7 bridges. All bridges are 2mm thick. The Longest bridge is 44.91mm long. The second longest bridge is 43.17mm. The third longest is 41.29mm long. The middle bridge is 39.42mm long. 3rd shortest is 37.54mm long. The 2nd shortest is 35.64mm long. The shortest one is 33.79 mm long. I made this in Fusion 360 and checked the length of the bridges in tinkercad.
