Introduction
Finally this part of the PiIoT project is almost complete! All the 3D printed elements are ready to be assembled but not all can be done yet. With the top and bottom - the two biggest layers - complete, before adding the moving parts the motors will be setup correctly and the firmware completed. In the meantime the rest of the project goes on ...
The most relevant post already published showing all the components is PiIoT - The perfect reading place #13 [tech]: Art-a-tronic, the base and motors holders
Preparing the base
A reminder: the image below shows the rendered3D model
As the rest of the opera the finished Art-a-tronic is built of four main sectors. To keep together the four parts of the base a 5 mm compressed wood with white plastic laminate surface is used as bottom support. The image gallery below shows the construction phases.

The first piece fit in place. Every sector is fixed to the base with four screw. When the entire building is complete, the base will also be glued for better stability |

Preparing the top frame
The most of the weight and mechanical stress should be supported by the base where the motors will be assembled further. The top frame is the visible white area of the opera and virtually has no stress but staying in place. For this reason this part has been printed with just a 25% of internal fill. To keep the four sectors flat and perfectly aligned - it is essential for the mechanic working properly - two different fixing methods bas been adopted: a screwed double support on the perimeter and a back dowel in the center.
The image gallery below shows the assembly phases of the top frame.
