PROJECT: Small plastic snap-fit applicator prototype for lip balm tube (U.S.-based only) Budget: $150–$200 I need a simple, clean physical prototype of a small plastic applicator that clips onto a standard lip balm tube (ChapStick-style for reference, ~15–16 mm diameter). Scope: • Create basic CAD model (STEP + STL) • 3D print physical prototypes • Ship to me (U.S.) • 1 minor revision if needed after test fit Design overview: • Small, slim tool (~44 mm length) • Designed to clip onto a cylindrical lip balm tube (~15–16 mm diameter) • Clip is a half-circle (C-shape), not a full ring • Include a small opening gap so it can snap on and off • Should hold securely but not be overly tight Reference note: • I have renderings for reference only. They show general shape and surface quality, not final design or exact geometry • I will also provide photos of a simple physical mockup to guide proportions Retention method: • Use a pressure snap-fit (slight inward tension) • Include light internal ribs or contact lines for grip • Do NOT use aggressive locking beads or hard snap features • Goal is secure but smooth attach/remove Body: • Thin, low-profile (~1.0–1.5 mm wall) • Slightly curved to follow the tube surface • Not bulky Applicator tip: • Integrated into the top of the body (not a separate piece) • Smooth, rounded, slightly tapered • Subtle raised contour (~0.5–0.75 mm), fully blended into surface • Narrow enough to enter a small opening and reach below an internal platform and around the screw mechanism Prototypes: • Provide 2–3 physical samples • Slight variations in tip height/shape for comparison and snap fit tensions Finish: • Clean and smooth (no rough or stringy print) • Prefer resin (SLA) or similar smooth finish • Matte neutral color (gray preferably) Requirements: • Must be located in the United States • Must be available for a short phone call to review details • Must have a mechanical engineering, product design, or industrial design background • Experience with small plastic parts and snap-fit features required Screening: • Please briefly describe your experience with snap-fit or clip-on plastic parts • Include an example of similar work if available Goal: This is an evaluation sample to demonstrate concept and basic function, not final production. Please include: • Relevant examples of similar work • Confirmation you can provide multiple samples • Estimated turnaround time

Hello ✅ Can you confirm snap-fit tolerance range (± mm) to control retention force on 15–16 mm tube? ✅ Should internal ribs follow longitudinal lines or discrete contact points to avoid stress whitening? I can design a precise snap-fit C-clip using controlled interference, flexible wall thickness (1.0–1.5 mm), and tuned rib geometry for smooth attach/removal. I have strong experience in small plastic parts, SLA prototyping, and snap-fit mechanics with optimized strain limits to prevent cracking. I will deliver clean STEP/STL, 2–3 SLA prototypes with slight fit/tip variations, and ensure smooth matte finish ready for testing. Let’s connect briefly to review your mockups and finalize fit details. Best regards, Mohand

The challenge here is delivering a prototype that nails precise snap-fit tension and sleek ergonomics on a tight diameter, eliminating function guesswork and saving costly redesigns. I specialize in engineering plastic clips with tailored internal ribs and exact tolerances that clip securely but slide off smoothly, all optimized in CAD for flawless 3D printed prototypes. I will create an accurate CAD model with critical pressure-fit features, 3D print 3 resin samples varying tip profiles and snap tension, and ship promptly within the US. After your test fit, I will fine-tune one revision to guarantee perfect grip and ease of use without bulk or roughness, following your exact specifications and photos. What’s your preferred timeline for receiving the initial printed samples to schedule our call and clarify fit expectations?
