Description
These are tail fins for model rockets.
Instructions
Print it out on a 3D-printer and glue it around the end of the body-tube of your model rocket.
In the OpenSCAD file, you can easily change all relevant parameters (number and size of fins, diameter of the tube, ...).
The .stl-file is for a rocket with a 20 mm body tube with 4 fins tapering from 50 mm down to 30 mm. The span is 80 mm.
CAUTION: I had some trouble when printig these thin fins. They seem to split easily. For me, it worked best with a brim at the bottom, cooling fan OFF and some cardboard boxes positioned around the printer to avoid any airdraft. YMMV.
