I had designed this to prevent grass, dirt, etc. from getting inside of the motors when landing. Once I put them on, I noticed a significant improvement. Also, they did not affect the flight characteristics or performance. You can print the front and back motor protectors different colors for better visibility. Best of all, they hold up suprisingly well!
To install the motor protectors, first remove the four screws underneath the motor. Then slide in the motor protector and install the screws.
I am 17 years old and I started with 3D printing in March of 2017. This all started with some inspiration and motivation, which came from school and youtube videos. I own the Anet A8, which I feel all beginners should start with. It teaches you much more about 3D printing than just buying a pre-assembled one. My current interests include robotics, programming, designing, laser cutting and of course…3D printing.
