This is a fin alignment tool for model rockets. Markings are designed for 3 fin and 4 fin rockets, and fits bt20, bt50, bt60, and bt80 body tube sizes.

STL attached is in mm units already. Each step is approx 0.03 inches less than a perfectly snug fit- adjust up/down based on your printer's tolerances.
