The water bottle that I made for 22 years was also used for teaching.
The design uses anthropomorphic elements, the shape is similar to a little fat man wearing a hat (originally thought to be a Raper image), with obvious personality and interest.
This bottle is not produced either (the production cannot be distributed). It is purely for fun. Let's take a look. If you don't like it, you can spray it...

Modeling design:

Anthropomorphic modeling: The overall shape of the water bottle imitates a figure wearing a hat, including a rounded top similar to the head and a part below that simulates the legs, making the entire water bottle look like a standing little person.

Bottle cap design: The bottle cap is designed to resemble a stylish top hat, adding an elegant and eccentric temperament. The cap on the left side is removed, while the cap on the right side is worn on the bottle body, showing the open and closed states of the bottle.

Portable rope: The design includes a gray rope around the bottleneck, which is convenient for users to carry. It also enhances the overall fashion sense as part of the design.

Color Design:

The main color: the use of bright purple, this color is lively and full of charm, may attract young or pursuit of personality consumers.

Cap color: The color of the cap is consistent with the bottle body, forming a unified visual effect and emphasizing the continuity of the design.

Material Design:

Transparent material: The water bottle is made of transparent plastic material (mostly PP), which not only makes the liquid in the bottle clear at a glance, but also increases the beauty of the product.

Surface treatment: during rendering, the surface of the bottle body is added with a little water drop effect to increase the layering and simulate the condensation phenomenon that may occur in the use of the water bottle.
