3D CAD Product Designer

I am interested in creating a 3D CAD design for 2 different projects, both product construction designs. Please respond with samples of previous product designs and any examples of designs similar to either of these 2 projects.
1.A Dry Cold Plunge body encapsulating suit design designed to maintain cold temperatures around the body while preventing the cold from escaping. The material design of the suit could include an outer layer of Neoprene for durability and waterproofing, an insulating layer of Aerogel for superior thermal insulation, a cold retention layer of PCMs or gel packs to maintain cold temperatures, and an inner layer of Coolmax® for moisture management and comfort. I want to ensure that all layers are integrated in a way that allows for movement and flexibility while maintaining the thermal properties. I will need detailed specifications including thickness and lengths to design the prototypes for the suit and hope to have mock ups of each layer of the suit to illustrate the detail.
The concept is to make a suit that acts as a dry cold plunge, without the need for the water compartment used for this model ----------

2. For Buddha Pets, which are a plush toy design similar to the designs in the drive and would like to create a few new images in addition to improving the current images for the toys we already have samples for.
Here is a google drive folder with a few of the graphics to use as reference for the designs.
----------

We would like to create an example of each design and we are open to advice on design that will help us to improve the fabric and construction based on your recommendations. Our vision is to have the softest and most luxurious fabric possible along with a colorful, yet sophisticated design. Each Pet should be between 10cm-15cm wide and 12-18 inches tall so they are portable.
