A tried and tested turtle mode fin for your Five33 Tiny Trainer.

Print in TPU, 0.2mm layer height, no support.

Washers will be required to make the screw heads grip the fin strong enough during a crash.

I have included a new iteration of this fin, one that holds a Foxeer Lollipop antenna at the back, should print fine without support.

You can sell prints of this, but don't overcharge, and link back here. Tips are most welcome https://www.paypal.com/paypalme/Haku3D and will encourage me to make more designs for everyone to benefit.
