A business acquaintance had a used but significant piece of equipment in their printing business and needed a replacement part. Using a picture with the part next to a scale the picture was imported into Design Spark Mechanical and the 2D profile was traced and then extruded to the correct depths. DS-Mechanical worked quite well for scaling, tracing, extruding, and exporting the stl file.

The part was designed in metric and printed in ABS on a Makerbot Replicator.
