Bearing integration (for smooth and quiet motion)
Corrosion-resistant surface treatments

Deliverables

3D CAD Model: STEP (.stp) + native format (Inventor/SolidWorks preferred)

Exploded View: For assembly details
Bill of Materials (BOM): For CNC machining and polyurethane molding

Evaluation Criteria

Durability and load capacity
Manufacturing feasibility (CNC + polyurethane molding)

I have created designs that can be manufactured for you, production-ready files, and detailed technical drawings. I hope you like them.

What I require are real, manufacturable designs, production-ready files, and detailed technical drawings prepared according to engineering standards. I am not looking for conceptual or visual ideas, but for engineering documentation that can be directly used in the manufacturing process.

Let me know is this particularly for your suite case or common for all (std ), please give a clarity with reference image , max dia for the wheels will be 50-60 mm and height of the system is 60 mm ,then what about the mounting part,is it inside the wheel dia or can be project upper side .

After carefully reviewing the requirements the scope feels very large for a blind contest with a one hundred dollar prize. The requested work includes full three dimensional CAD models fully toleranced two dimensional manufacturing drawings exploded assembly views and a complete bill of materials along with consideration of load capacity CNC machining and polyurethane molding. This level of detail usually belongs to a paid product development stage rather than a concept level competition. The design itself is achievable from an engineering point of view however clearer guidance on whether a conceptual or production ready submission is expected and what target unit cost is being considered would help participants match their effort to the contest value. Providing this clarity would likely result in more realistic and technically sound submissions.

Are you allowed flip cuts with the CNC, or are we cutting once from one side?

To convert a wheelbarrow into drain silt carrier
We use wheel barrow to carry any solid item like construction material etc. . We need to convert it into a caarier of drain waste by adding fileration and small water storage. Idea is that during cleaning of open drain in small colony / gali , we dont have any carrier which can carry drain silt which is mixed with water therfore we had to kept it on the road and for drying. A wheelbarrow may be changed in acarrier which can drain the excess water and only solid waste remain in the carrier.
Compressor Valve Improvement
I have several designs for a compressor valve that I have been working on. I am looking now to manufacture based on a numnber of tests made. However, I have 2 designs that I need to decide to finalize. I would like to get good engineering feedback on the best option that will ensure no leakage and the longest operational running hours. These valves will run in a compressor and need to run for 16000hrs and longer.
