I've concentrated most of my focus on designs that I manufacture in house, but I've chosen to offer the many small parts and odd little bits, both practical and frivolous, here on Shapeways a sort of clearing house for my skills.
As such, you might notice some common themes. I love twisting and tweaking designs from the original to carry out their function while reflecting the changes to their reference. The easiest way to see this is my conversion badges. I take a lot of time replicating the original style but with new displacements and messaging.
I also greatly love purely mechanical items, like engines, and their intricacy. I hate placing plastic shields over things and pretending as if that's somehow a styling or design feat (I'm looking at you, modern automotive designers).
