The prompt

Create a simple, beginner-level 3D CAD concept for my school water-balloon launcher prototype. Use the original HANDHELD design: two people hold the elastic ends, and a third person pulls back and releases the pouch. Do NOT replace it with a wooden frame. The modification is an improved fabric pouch and positioning marks. Model these parts: • A shallow, open fabric pouch approximately 200 mm long × 160 mm wide. Represent it as a thin, slightly curved surface—not a rigid bowl. • A visible colored cross at the pouch’s center to show where the balloon goes. This is a marking, not a hole. • Two matching reinforced fabric tabs, one on each side, connecting to the existing elastic. • A small soft pull tab at the back. • Simple elastic tube shapes connected to basic loop handles. • One translucent oval representing the water balloon. Show: 1. An angled 3D view with clear labels for the pouch, center mark, side tabs, elastic, and handles. 2. A top-view layout showing the two holders, the person releasing, ground-position marks, and an arrow toward the target. Use labeled circles instead of detailed people. Keep it basic: simple shapes, a few colors, no realistic fabric simulation or detailed stitching. Do not add a frame, track, trigger, motor, or metal hooks on the pouch. Label holder spacing, pullback, and handle/pouch heights “teacher-approved / TBD.” Do not invent safe stretching limits. This is a preliminary visual prototype, not a tested launcher. Provide an editable CAD model if supported, along with the labeled views.
