UMX firewall motor mount

This is my first design! made on the first day I got my first 3D printer.

It is part of the motor mount system found in many UMX planes sold by Horizon as EFlite and Parkzone airplanes.

It accepts the std stick mount motors, or the CNC aluminum motor adaptor shafy as shown in these pictures.

My printer did not creat precision 5mm hole for the stick shaft, but I just heated up the hole with soldering iron and shoved the shaft in, and it worked.

In future I'd like to design a motor mount that eliminates the aluminum adaptor altogether, but I only know TInkerCAD for now, and it is too limited.
