3D printing

Designing a 3D model in Fusion 360

One part of the individual assignment for this week was to 3D print an object which could not be printed via subtractive design. I decided to print a box containing a rotating axle: Image

To design this box, I started off by extruding a square to make the base design, and created a hole in the middle with another sketch. Then, I created two holes at the edges, and created a sketch to represent the axle and revolved it around the line between the two holes. I could have also used the Loft feature instead. Finally, I extruded a cylinder on top of the axle so that I could see it rotating.

Printing out the part

After exporting from Fusion 360, I used PrusaSlicer to slice the part and convert it to a gcode file. I then sent it to one of the Prusa Mini printers at the lab via the OctoPrint web interface.
