2019 Science Olympiad Elastic Launch Glider Gage

thingiverse

When supervising Science Olympiad contestants, I speed-check planes by making precision gages. These gages used to be crafted from balsa and foam board, but with the advent of 3D printing technology, that approach is now absurd. I currently design these gages in 3D format to share and print them using my own 3D printer for my convenience. To accommodate the printer's limitations, I divide each gage into two sections, which are then reassembled with 3.5mm bolts after printing. To facilitate use, note that the narrow gap represents the maximum wing chord, while the wider gap signifies the minimum fuselage length required to secure a bonus. The critical detail is that the fuselage's length must not fit within this gap in order to qualify for the bonus award.
