For this project, we had to design something using OnShape, so I decided to create a simple water bottle. For this project, I did not use AI to help me.
This water bottle is a simple hollow cylinder with a more complex lid. The lid is designed to fit on top of the cylinder in a way that prevents it from falling off to the side as well as preventing spillage while attached.
One of the first things I did for this assignment was to sketch out the radius of the cylinder, as well as the inner circle that is going to be hollow. Above that, where the end of the cylinder would be, I added a small ring for the lid to fit around.
The next step for the cylinder was to extrude it. First, I extruded the ring that formed the cylinder and adjusted the depth of the extrusion. Then, I added a base by extruding the inner hollow circle of the cylinder about 1/15th the depth of the original cylinder. Finally, I extruded the small ring at the top by 1/10th of the original cylinder’s length.
For the lid, I followed the same steps, creating a sketch, extruding it, and creating more sketches and extrusions as I went along to create a more complex shape.
Once both parts were complete, I opened an assembly and placed both parts together. I used a mate connector to see if they fit, and then set up an animated mate that shows how the lid goes on.
Once this was done, I created a drawing in OnShape and inserted various angles and views of the two parts into it. I used the measurement tool to show the exact measurements required to recreate the parts.
In this drawing, I added a BOM, or Bill Of Materials. For this, I decided to make both parts out of stainless steel, due to its durability and lack of microplastics.
