Nekoosa Mobility Walker (Version 2)

Inspired by the "Open-Source Designs for Distributed Manufacturing of Low-Cost Customized Walkers" article, our Drafting class has been working on a 100% plastic walker.

Our goal for this project is to make a strong, customizable mobility walker for $20 material cost.

After building the open source walker, we realized that most of the material cost was from the wooden dowels. Initial print-volume calculations and FEA simulation showed us that we could build an all-plastic walker that was stronger and less expensive than the partially wooden one.

Ideas for the initial design's structure were derived by topology optimization via Fusion 360 simulation. These generative design structures were discussed by the Drafting class and a refined 3D model was built and tested at 1/5 scale.

The design was refined over many iterations; the final iteration is able to nest with more versions of itself, like a shopping cart.
