The prompt
Create an editable, dimensionally accurate 3D-printable CAD model of a transparent mechanical clip for an electronic trading-card price tag. **PURPOSE** The clip attaches to the upper-right corner of a standard Ultra PRO 3" × 4" (35pt) trading-card toploader. It must securely hold a removable electronic price tag without damaging the toploader or contacting the trading card. **TOPLOADER DIMENSIONS** - Joined plastic edge thickness: 1.59 mm (1/16 inch). - Available plastic border width: 3.175 mm (1/8 inch). - Attachment location: upper-right corner. - All gripping surfaces must remain within the available plastic border. **CLIP DESIGN** - Completely transparent appearance. - C-shaped mechanical clip that grips both front and back surfaces of the toploader. - Rounded, smooth contact surfaces. - Broad contact areas to distribute gripping force. - Flexible spring section for controlled clamping pressure. - Small mechanical retention lips to prevent accidental detachment. - Opening must accommodate the toploader without excessive compression. - Strong grip without cracking, scratching, or excessively flexing the plastic. - No adhesives or magnets. **ELECTRONIC TAG MOUNT** - Include a compact integrated sliding attachment rail on the outward-facing side of the clip. - Rail must accept a separate removable electronic price tag. - Include a positive mechanical locking feature to prevent the tag from falling off. - Allow intentional removal for charging and replacement. - Keep the attachment within the outer footprint of the toploader. **DESIGN PRIORITIES** 1. Secure retention during repeated handling and transportation. 2. No contact with the trading card. 3. No excessive pressure on the toploader. 4. Minimal size and visual obstruction. 5. Durable construction suitable for repeated use. Create the clip and mounting rail as editable CAD geometry with adjustable dimensions. Show front, rear, side, and isometric views. Do not create the electronic display itself. Focus exclusively on the transparent mechanical clip and its attachment rail.
