I think this is the hardest part of the project. Thanks for all the team to help me to realize this part. I have already use some 3D modeling software like Solidworks or Catia, but they are not free, so they do not enter on my processus for this project.

We used Blender and FreeCAD to model all parts (not the head, because an other guy model it for me some month before).

You can download all 3D files in multiple format here : https://github.com/AmarOk1412/GLaDOsReplica/tree/master/Maquette%203D

To print all parts you can use the software replicatorG : http://replicat.org/

To print all parts we use 3 printers. (2*Replicator 2x + 1*Reprap).

P.S. : Some part are very long to print (50 hours for the base).
