Bottle reverse engineering

BOTTLE

I started by sketching a rough jagged shape of half the bottle, making sure that the entire bottle is above the horizontal line as a water bottle is usually placed on top of a desk or a surface while following the instruction precisely for measurements in order to create a replica of the Earthwell bottle. Next, I used the sketch fillet tool to create curvatures on the bottle. The measurements icludes a 3mm radius fillet near the neck of the bottle and a 10mm fillet where the neck merges with the body.

To bring the shape out to be 3D I started by selecting the entire sketch and with the revolve tool I am able to revolve the object around the center line. Next, I used the shell tool and set the wall thickness to 2.5mm creating a hollow object this can then be viewed using section view.

LID AND O-RING

To sketch half the lid I followed the instruction precisely in order to get an accurate results. some of these important measurements includes 47mm from top to bottom of the lid and the 2.8mm gap between the lid and body for the O-ring.

The revolve tool is then used again to create a general shape of the lid. Afterward, I fillet to the top edge of the lid to have a radius of 2.5mm and the bottom to have 1.5mm.

On the physical earthwell bottle the top area is made out of wood which means I would have to split the top surface of the lid into 2 parts. This is done with the tool plane tool and offsetting it 2.5mm downward along with the split tool which separates the parts.

To create the O-ring I sketched a semi-circle with a radius of 1.5mm using the 3 point circle tool I then used the revolve tool once again in order to circulate the shape around the lid.

HELIX

To start creating a Helix I created an offset plane of 12.5mm from the rim.

Next, I slected the plane created and then with the project tool I was able to highlight the inside diameter of the bottle neck which will later become a reference for my helix.

I then used the search bar to search for the helix tool and with the instruction given I applied the instruction above onto my bottle.

Afterward I selected the spiral as well as the end point of the spiral which allows me to create a plane perpendicualr to the point.

Using the plane I was able to draw a circle with a diameter of 3mm on the start point of the helix. Next, with the sweep tool I was able to bring the helix out in 3D form.

LID THREAD

To create the thread to the lid I hid the rest of the bottle and with the plane tool created an offset plane 6.5mm from the bottom of the lid.

Afterward, I sketched a circle with on to the plane I created and with the Helix tool I am able to apply these setting which creates a helix complimentary to the body.

HANDLE

To start the handle I sketched the shape of the handle with straight lines first, I then make sure to get the accurate angles and dimensions using the dimension tool.

Next, I created a curve point plane by selecting the point and the line connecting the handle to the lid. Afterward, I used the plane created in order to sketch a 4mm diameter circle with the selected point as the center.

I then selected the circle and with the sweep tool I selected all the handle's sketch line which brings the handle to 3D form.

With the offset tool I am able to create a circle that is bigger than the handle sweep by 0.33mm which is the tolerance to allow the handle to fit. Next I used the extrude remove tool to create the hole and duplicate it over to the other side using the right plane as the mirror plane.
