3D Design for Advanced Cooler Box

I'm looking for a product designer with mechanical engineering experience to draw a 3D printable design for a cooler box. You'll need to offer advice on how to improve the product. I will provide an image of how the shape of the product should look like.

Key features of the cooler box:
- Drainage spout
- Air inlet and outlet with built-in fan
- On/Off switch
- Removable battery inlet

Necessary skills and experience:
- Product design
- Mechanical engineering
- 3D modeling
- Prototyping

Please only apply if you can provide design improvements and have relevant experience.
