3D CAD Game Prototype Design

I'm seeking an experienced CAD designer to create a 3D model for a collapsible, four-sided soccer-style target game.

Game features:
- Modular plastic frame
- Four fixed, inward-facing semi-circular goals with mesh netting
- X-shaped base frame for center support
- Foldable or disassemblable design for portability
- Estimated dimensions: ~70cm x 70cm x 50cm

I will provide:
- Hand-drawn sketches or reference images
- Dimensions and materials
- Clarifications via message or Zoom

Requirements:
- Clean 3D CAD file in STL or STEP format
- Collapsible functionality or modular joints as needed
- Use of snap-fit joints for collapsibility

Please note: I’ve enabled the Freelancer.com IP Agreement upgrade. I’ll only award the project to someone who agrees to that.
