About this 3D model

This part was made with Tinkercad. Edit the part online at: https://tinkercad.com/things/99ggSiYgxlZ The assembled example has some colouring issues but it's just for the sake of the picture. It was originally covered in scales but they kept disappearing. I'm not having much luck with tinkercad working the way it is supposed to. If i can get tinkercad to cooperate I will load a full set version for download...
