Mechanical design of infrared spectrometry rigs. From complex parts with specific finishes and tolerances (such as reflection chamber, interference fitted parts and channels for o-rings) to more trivial parts such as funnels and thumbscrews. These parts were machined on a variety of materials (Stainless Steel, Aluminum, Teflon) or 3D printed.
3D printed model.
Stainless steel mesh filter.
Some parts went through multiple iterations design wise, although not all were fabricated.
