CAD Drawing for Carabiner Silicone Case

I need a precise CAD drawing that incorporates a carabiner point onto the CAD drawing of the silicone glasses case, based on the provided image and data:

Please make a teardrop Carabiner with a 6.0 mm inner hole, 12.8 mm total height, 3.0 mm wall thickness, and 4.0 mm part thickness. Angle the Carabiner 40 degrees upward and blend it smoothly into the top corner of the case with a strong rounded base.

Hole size (inside diameter): 6.0 mm
Overall eyelet height: 12.8 mm
Carabiner wall thickness: 3.0 mm
Carabiner body thickness: 4.0 mm
Angle: 40° upward
Shape: smooth teardrop
Transition into case: soft blended fillet, no sharp corners

Important notes
The Carabiner must be integrated smoothly into the case body
The base where it joins the case must be reinforced
Please keep all surfaces smooth and rounded
No sharp edges inside or outside the hole
The Carabiner should look like part of the mould, not added on afterwards

Requirements:
- Dimensions of the carabiner point are essential.
- The carabiner point should have a round shape.
- Placement of the carabiner point should be on the side of the case.

Ideal skills and experience:
- Proficiency in CAD software
- Experience in designing silicone cases
- Attention to detail and accuracy
