Concept Model: a perfume bottle machined with a 6mm ball-ended cutter in rigid closed-cell modelling foam. Two halves were machined and then glued together. The toolpaths and code were created in DeskProto. The STL format file for geometry of the bottle is a sample supplied with DeskProto. A post processor for DeskProto is available from WELsoft.
