Stride: Customisable Futuristic 3D Printed Crutch

#Stride: Customisable Futuristic 3D Printed Crutch

DISCLAIMER: NOT FOR MEDICAL USE. FOR EDUCATIONAL PURPOSES ONLY.

This customisable 3D-printed crutch was created as a case study demonstrator for an additive manufacturing MSc project on "Using Computational Methods to Design, Analyse, and Optimise a 3D-printed Crutch".

You can also refer to the attached report, presentation slides, and flyer for more information on how we created this crutch.

The total cost to make this crutch was £44.34 (~55 USD). But you can repurpose discarded or unwanted crutches to reduce the cost to about £14.34 (~18 USD).

All STL files have been oriented to minimise the amount of supports required.
