3D printing

For this assignment, I decided to model and print a pulley for my MakerFight robot. It will be a T5 pulley with 20 teeth.

3D Modeling

I used Fusion 360 to model my part. You can see it below :

After that I exported my part into CURA to print it.

Here you can find the source file STL.
