Foldable A-Frame Stand (Base, Struts, Pin & Roller Joints)

Create a simple 3D CAD model of a foldable stand that closely matches the uploaded reference image. **Design requirements:** 1. **Overall shape:** Keep the same shape, proportions, and arrangement as the reference image. Do not redesign or add unnecessary components. 2. **Base:** Create a flat rectangular base with raised side edges and a central slotted platform, matching the image. 3. **Support structure:** Create two long, inclined support members forming an A-frame structure, connected near the top and attached to the base. 4. **Folding mechanism:** Make the support members fold using simple pin-and-roller joints. Use a small cylindrical roller mounted on a pin at each required folding location. The roller should rotate freely and reduce friction during folding. 5. **Material consideration:** The stand will be 3D printed. Do not use flexible printed hinges or require the printed parts to bend. All folding movement must occur through mechanical joints. 6. **Keep it simple:** Use only the necessary parts: base, support members, rollers, pins, and simple stops if required. Avoid complex linkages, curved tracks, and unnecessary brackets. 7. **Assembly:** Keep the base and support members as separate components where necessary. Ensure that the joints allow the stand to fold and unfold without parts colliding. 8. **Modelling approach:** Use basic CAD features such as extrusions, holes, slots, and cylindrical pins. Follow the reference image as closely as possible. **Final output:** A clean, editable 3D CAD assembly with realistic folding joints. Prioritize similarity to the reference image, simple geometry, and ease of 3D printing over decorative details.
