Our last third year project , we were tasked with designing a hand mixer. We had to reuse the internals of an existing hand mixer to create a working hand mixer of our own relating to a given theme , mine was floral.
These are some examples of my explanatory drawings. They were created with Blender , Photoshop , Illustrator and Sketchbook.
Some of my engineering drawings for my mixer , created in Solidworks .

The renders were created in blender . I'm quite pleased with the first four renders . They took longer than I would like to admit to particularity because there was a lot I had to learn and there was lots of tweaking. The last two could use some improvement and their poor quality was due to time constraints. Feel free to give critique.
