Mechanical CAD Engineer Needed to Review & Complete Existing Product for Manufacturing

I am a product developer seeking an experienced Mechanical CAD Engineer / Product
Design Engineer to review and complete the existing CAD files for a patented consumer
product called Lock-It.

The product has already been designed, and CAD files have been created. I am not looking to
redesign the product from scratch.

I am currently communicating with manufacturers and have been asked to provide additional
manufacturing documentation, including 2D technical drawings in PDF format and
step-by-step assembly instructions with images.

I am looking for someone who can review my existing CAD files, identify anything that is missing
or needs correction, and prepare a professional manufacturer-ready engineering package
that can be submitted for quotation and eventual production.

Scope of Work

The selected engineer should be able to assist with:

● Review of my existing CAD/STEP files for completeness and manufacturability
● Correcting or updating existing CAD files where necessary
● Preparing manufacturer-ready STEP files for the individual components
● Creating professional 2D dimensioned technical drawings in PDF format
● Adding appropriate dimensions, tolerances, materials, finishes, and manufacturing notes
● Creating an exploded assembly drawing
● Preparing or reviewing the Bill of Materials (BOM)
● Creating step-by-step assembly instructions with images/illustrations
● Reviewing the design from a DFM (Design for Manufacturing) perspective
● Identifying any potential manufacturing issues before the files are submitted for
production
● Preparing an organized final engineering package that I can provide to Xometry and
other manufacturers for accurate quotations

The product consists of a small molded plastic enclosure measuring approximately 2" L × 1.5"
W × 0.5" T, a plastic-coated braided-steel cable approximately 20 inches in length, and a
locking mechanism. Final dimensions, component specifications, and other technical details
should be verified against the existing CAD files.

Ideal Candidate

I am specifically looking for someone with experience in:
● Mechanical engineering or mechanical CAD design
● Consumer product development
● Injection-molded plastic parts
● DFM / Design for Manufacturing
● 2D manufacturing drawings
● GD&T and tolerancing where appropriate
● Assembly drawings and assembly documentation
● Preparing CAD packages for manufacturers
Experience working with Xometry, Protolabs, injection molding companies, or contract
manufacturers would be a plus.

Important

I already have existing CAD files and product renderings. This project is primarily about
reviewing, correcting, documenting, and preparing the existing design for manufacturing,
rather than creating an entirely new product.

Because this is a patented product moving toward commercialization, confidentiality and
professional handling of the design files are important.

When applying, please provide:

1. Examples of similar consumer or mechanical products you have prepared for
manufacturing.
2. Examples of your 2D technical/manufacturing drawings.
3. Your experience with injection-molded plastic products and DFM.
4. Whether you can create assembly drawings and step-by-step assembly instructions.
5. Your estimated cost and turnaround time after reviewing the existing files.
6. Whether you would be comfortable reviewing the existing files first and identifying
exactly what is needed before beginning the full project.

My goal is to establish a relationship with a reliable CAD/mechanical engineer who may also be
available for future manufacturing revisions as the Lock-It product moves toward production.

Thank you, and I look forward to reviewing your qualifications.
