CAD Design for Protective Household Clip

I need a CAD design for a simple, three-sided plastic clip intended for household use. This clip should have EVA foam on the interior surface, providing a cushioning effect, to protect it from scratching the glass surface it is inserted on. One exterior side will also have a foam layer to cushion the glass that will be resting on it. It will be used to be pushed onto the fixed panel of a glass shower enclosure allowing the shower door to rest on the foam covered exterior side of the clip to allow air to circulate promoting drying of the shower and glass panels. It is intended to be slid on and off and needed.

I have attached a simple drawing. These specs are preliminary but close enough, I think, to support developing and estimate. I will likely need to have multiple prototypes developed for testing.

Key Deliverables:
- A CAD design for the clip
- Specifications for the EVA foam to be used
- Consideration for the clip's protective function

Ideal Skills and Experience:
- Proficient in CAD software
- Experience in product design, particularly for household items
- Understanding of materials, specifically EVA foam
- Ability to design with a focus on product durability and protection.
