The system is full assembled using the mechanical positioner and a heavy base, etc

V5 was printed
Everything assembled and connectorized.
Looks very good, next step is test using the driver.
16/01/2014
A deviation on the Z-axis movement was see during the tests, almost 50% of the Z movement range can be seen on the XY-plane. This effect is highly undesired and its origin is not exactly known. The assumption is that the poor quality of the bases supports and the unbalance of the springs are the origin of this problem.
The tests also revealed a problem with the Upper_Base_V4. The piezo tube is rotate by 45 degrees from the right position.
Piezo tube and Upper_Base coupling alignment corrected, I also increase the coupling depth, it might improve the alignment. New version: Upper_base_V5
The same increase in the coupling depth was made at the bottom_base. New version: Bottom_base_V3

Assembling the complete system.
Piezo Tube glued with Silicone I (GE), need to wait 24h before testing.
09/01/2014
The changes worked, now there are space for the wires and the solder
08/01/2014
The new Top_Base part was printed by Daniel and Mateus.
The coupling with the piezo tube is working now. The soldering on the tube difficult the assembling and the diameters are a little loose, but it will not interfere with the assembling.
Changes made on the design, new version V4 was finished and sent to be printed by Daniel

The part "Upper_base_V3.SLDPRT" need to be printed to test the coupling with the piezo tube.
https://www.dropbox.com/sh/37igxe93yse6c7d/21vgUsHyYi
Bases used to sustain the print process were changed to 0.2mm
