I've always found bike fenders to be annoying - both in aesthetics and function. This project was a disruptive proposal, designed for a specific manufacturing technique: 3D printing. This allows for much more customization options, adapting it to match the user's bike through shape design, color and material choice. Being fully printable within 1.5h without any waste material, the product is above all a sustainable alternative, as it is produced within a reasonable time-frame and without overproduction. The fender itself is easily collapsible and removable, meaning that it can be taken off at any point, and if any part should break it can easily be replaced for a fraction of the initial cost and production time.
