Non-cylindrical Bottle (lid)

On the weekend following week 3 I modelled the lid for the non-cylindrical bottle.

The lid is made from a single piece of plastic but has a hinge.

 I decided to model it as two separate parts then mate them together in an assembly.

I began with a loft to create the main body of the bottom part. I measured the width of material and the details on and around the top with a vernier caliper.

I then measured and created the top part of the lid.

I returned to the bottom lid part and used visual approximations and logical assumptions (based on the top of the bottle body) to model the interior details.

With the bottle body and both lid parts completed, I create an assembly to bring them together. I completely mated the bottom lid part to the main body part, preventing it from moving. 

I mated the hinge details of the two lid parts, allowing an opening/closing motion.

Some of the dimensions around the body lip/lid interior details needed adjusting to ensure the parts were not intersecting.

Altogether this bottle took many hours to model, but I found the work interesting and actually enjoyed seeing how far I could push the program. I actually surprised myself with my skills and abilities; I would not have thought that I could produce such a complex and accurate model.
