2020 Science Olympiad Elastic Launch Glider Gage

As a Science Olympiad Supervisor, I speed-check planes by creating precision-made gages. Gone are the days of crafting them from balsa and foam board; with the advent of 3D printing, that's simply outdated. Nowadays, I design these gages in 3D, sharing and printing them on my own 3D printer for convenient use. To accommodate my printer, I divide each gage into two pieces, securing them together with 3.5mm bolts. For easy reference, I've included both the segmented files and a complete, uncut version of the gages. Here's how to use them: The narrow gap represents the maximum wing chord; the wing must fit within this space without touching. The wider gap signifies the minimum fuselage length required for bonus points. To earn those extra points, make sure the fuselage is too long to fit in the gap.
