At a previous job I was tasked with redesigning the models they gave to their sales force to demonstrate to potential customers how their products worked.
The original design was bulky, simple, and didn’t look very professional. It had feet that would fall off slide around while using the demo model.
My design incorporates all the requested design changes. Including a reduced form factor, better feet, and reflects real life more accurately.
I handled every aspect of the design and manufacturing process: from designing the CAD model to finding suppliers for the parts to assembling the models.
