CAD Designer Needed — Split-Sphere Impact Ball (Injection Mouldable) I need a mechanical/CAD engineer to create a mould-ready STEP file for a 45 mm diameter split-sphere toy made from two interlocking hemispheres. The product must be injection-mouldable and designed for repeated high-impact use. Required Deliverables: Mould-ready STEP file (primary output) STL file for 3D printing Simple 2D dimension drawing (wall thickness, tolerances, draft angles, parting line) Confirmation that the design is suitable for a two-part injection mould Geometry Requirements: Outer diameter: 45 mm (acceptable range: 44–47 mm) Wall thickness: 2.0–2.5 mm Smooth spherical exterior Central through-bore (6–8 mm) that aligns perfectly when assembled Two hemispheres connected using an underlapping lip seam with friction/interference fit No metal components, screws or magnets Manufacturing Requirements: Fully injection-mouldable (two-part tool preferred) Proper draft angles on all features (1–2°) No unnecessary undercuts Design compatible with PC-ABS or ABS Must support impact durability and drop testing Functional Requirements: Ball must stay closed during impact, swinging, twisting Must be easy to open by hand (child-safe) Closure should not loosen after repeated opening/closing cycles Additional Notes: I will provide full written specifications Looking for clean, factory-ready engineering files, not concept art Please include your estimated timeline and workflow in your proposal All deliverables will become the exclusive property of the client upon payment.

As a Manufacturing and industrial Engineer experienced in injection-mouldable consumer products, I can deliver a fully engineered, mould-ready STEP model of your 45 mm split-sphere impact ball, built to withstand repeated high-impact use. I will design both hemispheres with correct draft angles, a clean two-part tool parting line, a precise underlapping friction-fit seam, and a central through-bore that aligns perfectly when assembled. Wall thickness, shrink considerations, and material behaviour for PC-ABS/ABS will all be incorporated, ensuring durability and manufacturability without unnecessary undercuts. Along with the final STEP file, I will provide an STL for quick 3D-print validation and a simple 2D drawing documenting dimensions, tolerances, wall thickness, and draft. My workflow includes: (1) receipt of your specifications, (2) initial CAD build, (3) client review, (4) one revision round, and (5) delivery of factory-ready files. Typical turnaround is fast, and all rights transfer to you upon payment.

Hello, I’m Ebrahem Hassan, a Mechatronics Engineer specializing in manufacturable CAD design, durable mechanisms, and plastic part engineering. I’d be excited to create your mould-ready split-sphere impact ball with clean, factory-ready files that meet injection-moulding standards. I understand that this product needs to be simple, strong, child-safe, and optimized for two-part tooling. My experience designing sheet-metal and plastic assemblies for robotics, CNC, and 3D printing allows me to create geometry that balances strength, usability, and manufacturability without unnecessary undercuts. My approach will be to model both hemispheres with precise wall thickness, draft angles, and a clean parting line. The friction-fit seam will use an underlapping lip that stays secure under impact yet opens smoothly by hand. I’ll ensure the 6–8 mm bore aligns perfectly and maintains structural integrity during drops, swinging forces, and repeated cycles. You’ll receive: • A mould-ready STEP file optimized for a two-part injection mould • STL files for rapid 3D-print testing • Simple dimension drawing with tolerances, draft angles, and wall thickness • Confirmation of mouldability and interference-fit performance • Clean, organized engineering ready for factory production If you want a precise, robust, and production-focused design for your impact ball, I’d be glad to deliver a complete engineering package.

Hello! I can design your 45 mm split-sphere impact ball as a fully injection-mouldable, factory-ready CAD model. I’ll create a STEP file suitable for a two-part mould, ensuring proper draft angles, wall thickness (2–2.5 mm), and a smooth spherical exterior. The central through-bore (6–8 mm) and interlocking hemispheres with friction-fit lip will be precisely aligned for repeated high-impact use, while remaining easy and safe to open by hand. I’ll also provide an STL file for 3D printing and a 2D dimension drawing showing wall thickness, tolerances, parting line, and draft angles. The design will be compatible with PC-ABS or ABS, free of undercuts, and optimized for impact durability and repeated opening cycles. Deliverables will be clean, manufacturable, and fully ready for tooling. Important Questions Can you confirm the target material (PC-ABS vs ABS)? Any preferred interference tolerance for the friction-fit? Required finish (smooth, matte, or textured)? Timeline for review and final delivery?

Dear Client ❤️❤️❤️. Hire ME! I’d love to help turn your 45 mm split-sphere concept into a fully mould-ready design. I can create precise STEP and STL files, a clean 2D drawing showing wall thickness, tolerances, and draft angles, and ensure the hemispheres interlock perfectly with a friction-fit seam. Everything will be injection-mouldable, impact-resistant, and child-safe, ready for production. Once we confirm the design, you’ll have factory-ready files you can hand straight to a mould maker.

Hello, expert is here! Picture the finished impact ball: smooth, perfectly spherical, and able to handle repeated drops and twists. I can create a mould-ready CAD model that balances wall thickness, draft angles, and friction-fit tolerances, producing both STEP and STL files along with a simple 2D drawing. The design will be ready for a two-part injection mould, child-safe, and durable for repeated play. Full timeline and workflow included so you know exactly when you’ll have production-ready files.

Hello, and thank you for outlining your requirements so clearly. I can deliver a fully engineered, mould-ready CAD package for your 45 mm split-sphere impact ball, designed specifically for injection moulding and repeated high-impact use. My workflow is built around manufacturability, precision, and clean industrial design. I will create both hemispheres with the correct wall thickness, functional tolerances, friction-fit lip geometry, parting line logic, and draft angles to ensure smooth release from a standard two part tool. The central through-bore will be aligned perfectly in both halves, with internal geometry optimized for strength, durability, and repeated open/close cycles without loosening. Deliverables include: • A mould-ready STEP file suitable for tooling • STL file for test 3D printing • 2D dimension drawings showing wall thickness, draft, tolerances, and assembly alignment • Confirmation of full injection-mould compatibility with ABS/PC-ABS and no undercut issues I focus on producing clean, factory ready engineering files no unnecessary design flourishes, only practical, production feasible geometry. The final design will remain secure during impact, twisting, and swinging, yet still open comfortably by hand. My timeline and workflow are structured around iterative review: initial concept geometry, fit & tolerance refinement, manufacturability checks, final production package. I’d be happy to begin as soon as you share the remaining specifications.
