During the Spring semester one of my classmates asked me to create a piece for his father’s Oldsmobile; this was a coupling used for the car’s automatic seat adjustment. The original piece was cracked and held together with scotch tape. I used this piece to measure with a caliper and created the piece with Solidworks. Obviously I used the 3 point arc to create the feature and the ‘keyhole’ was a pretty simple shape to make. Unfortunately I don’t have the Solidworks file anymore but I think I have the .stl file.
