# Scale model - Bourjault's ballpoint pen

This directory contains the original (left) and simplified (right) FreeCAD models of Bourjault's ballpoint pen used by the [ACRO](https://iiw.kuleuven.be/onderzoek/acro) research unit ([KU Leuven](https://www.kuleuven.be/kuleuven/)) to develop and test state-of-the-art assembly sequence planning algorithms. Each file is available in the .FCStd, .stp and .stl formats.
