Integrated flights/shaft, medium length, slim style flights. I wanted to see just how well dart flights printed at home could work. I tried other models and printed in a variety of materials. PLA and PETG broke immediately, however TPU printed very well and doesn't break. The problem I am running into now is that the shaft & fins aren't rigid enough to allow the dart to fly well. I will be experimenting with some stiffer yet flexible filament to see if I get better results.
