STIHL Shrub Shredder


spring 2017


3 weeks


umeå university

parametric modelling

80 hours

The main aim of the course was to learn Solidworks, with additional focus on branding and styling. The class were given a low cost grass/shrub trimmer, which was to be taken apart, inspected, and then the inside parts transferred into a new design. A suitable brand had to be chosen, analyzed through a brand board and then a new design was to be created with the original components in mind. Everything was modelled in Solidworks and finally 3D-printed .

short funny "commerical"

This was made during the Visual Storytelling Course, separately from the design and manufacturing of the model.

The time limit for the course was 80 hours, thus only 14 went into ideation.

Ideation was a back and forth process with several foam mock-ups, and measuring and re-measuring of the original components.

Total time spent  |  Final model


To ensure that everything would fit, all the original components were measured, built in Solidworks and finall placed inside the new shrub shredder design.
