My friends Reely Core Z RC car had a broken rear spoiler.
Remodeled the thing and printed it in TPU with 4 walls.
I uploaded a thicker version than the original because the TPU print with the original thickness is really soft even with 95A TPU.
Maybe this could fit on a Traxxas E-Revo too, but not tested.
The author marked this model as their own original creation.
