I sell a 3D-printed hard case for EpiPens. I need it redesigned to include a built-in Apple AirTag compartment so the case can be tracked if it's misplaced. I will supply the existing source file to work from. This is an *addition* to a working design, not a from-scratch rebuild — the existing case must be kept intact. **The task:** Add a purpose-built AirTag compartment that holds the tracker firmly with zero rattle, without adding noticeable bulk or introducing weak/fragile points. You can integrate it into an existing wall or as a low-profile external pod — your call, but show me your reasoning. **Requirements:** - Apple AirTag dimensions: 31.9 mm diameter × 8.0 mm thick. Design around these exactly, with a snug, retained fit (friction ring, snap lip, or captured pocket). - The AirTag must be **removable** for yearly battery changes — not permanently sealed in. - No rattle, no significant added bulk, no thin walls prone to cracking. The structural integrity of the original case must be maintained. - Must be FDM-printable, ideally without supports. Design for PETG at 0.2 mm layer height, with sensible wall thickness and ~0.2 mm clearance on the AirTag pocket. **Deliverables:** - Editable source CAD in **STEP** format (mandatory), plus your native file (F3D, Shapr3D, SolidWorks, etc.). - Print-ready **STL**. - Full commercial rights and ownership transferred to me on payment.

I’d be glad to upgrade your existing EpiPen case without disturbing the original design. I’ll add a secure, low-profile AirTag compartment with a removable retention feature, keeping the case strong, print-friendly, and practical for PETG, because a good tracker pocket should be invisible until it matters.

Hello, This is exactly the kind of product refinement I enjoy. Since your case is already working well, my focus will be on enhancing it rather than redesigning it. I'll preserve the original geometry while integrating an AirTag compartment that feels like it was part of the design from the beginning. The pocket will be engineered for a snug, rattle-free fit with approximately 0.2 mm clearance for PETG printing. I'll evaluate whether an integrated wall cavity or a low-profile external pod offers the best balance of strength, appearance, and printability, and I'll explain the reasoning behind the chosen approach. Battery replacement will remain simple without compromising retention. You'll receive the updated STEP model, native CAD file, print-ready STL, and complete commercial ownership upon project completion. I'd be excited to review your existing CAD file and get started.

Hi, I appreciate that you're not looking for a complete redesign—you already have a product that works. My job is to make the AirTag feel like a natural extension of that design. Here's my plan: • Preserve the original case geometry. • Design a secure AirTag pocket with zero movement. • Keep the profile as slim as possible. • Ensure PETG-friendly, support-free printing. • Maintain strong wall thickness throughout. • Deliver STEP, native CAD, and STL files. I'll pay close attention to structural integrity so the new feature doesn't introduce weak points or interfere with the existing function of the case. The final result will be clean, practical, and ready for production. I'd love to work on this upgrade. Thanks, Henry

Hi, I have strong experience modifying existing 3D-printable products and creating functional CAD designs optimized for FDM manufacturing. My biggest advantage is practicality — I can integrate a secure, low-profile AirTag compartment into your existing EpiPen case while preserving its strength, minimizing added bulk, and ensuring the AirTag is held firmly without rattle yet remains easily removable for battery replacement. The design will be optimized for PETG printing with appropriate clearances and wall thicknesses. This work fits me well because it requires careful product modification and print-ready CAD preparation rather than designing a new product from scratch. I can provide the updated model in STEP, native CAD, and STL formats. Best regards, Olena
