Expected duration: 3 - 4 weeks Job Title: CAD Designer Needed to Create 3D Printable Modular Marble Run Pieces
Description: I am looking for a mechanical CAD designer to help create a prototype design for a modular marble run. The goal is to design several marble run pieces that can connect and attach securely to each other so I can 3D print them and test the concept.
Scope of Work: • Create CAD designs for modular marble run pieces • Ensure pieces can connect together easily and securely • Design tracks so a standard marble rolls smoothly through the system • Parts must be optimised for 3D printing • Provide files suitable for prototype testing
Key Requirements: • Connection system between pieces (for example: clip fit, slot system, or similar) • Smooth slopes so the marble rolls consistently • Parts designed so they can be printed without complex supports if possible
Deliverables: • 3D CAD models • STL files ready for 3D printing • Native CAD files if available (Fusion 360 / SolidWorks / similar)
Project Notes: • I will provide sketches and explain the concept • This is for a prototype to test the idea, not final production design • Open to design suggestions from the engineer
Skills Required: • Mechanical CAD design • Experience designing 3D printable parts • Knowledge of tolerances and snap-fit or modular connections
Budget: Open to proposals (fixed price preferred)
NDA Requirement: Freelancer must sign a simple NDA before sketches or CAD details are shared. All CAD designs and files are the property of the client.
