3.1.1. Identification and Organization of Sub-Assemblies

In a first phase, it is necessary to organize the project into smaller and more manageable parts. For this, the different subassemblies that make up the PHI instrument assembly are grouped and a workspace is created in A360 for the management of the files. This consists in the creation of a Fusion 360 project that is shared with all the Fab Lab ULL team members who worked on this digital model. Thus, each member has access to all the information from the first moment. Furthermore, each person has one or more sub-assemblies assigned.

The classification and labelling system of the 17 sub-assemblies that structure the SO/PHI is essential. For this, transparent plastic containers with labels and with the plans for their manufacture are prepared to store, in an orderly manner, all the pieces that were going to be printed of each subassembly (see Figure 1).
