We should understand a way to avoid this problem to recur. It may happen at demo time, and we may not spot the problem easily

@fbiggi fixed the issue yesterday. The length of the screw was a bit too much touching the bottom of the threaded hole instead of tightening the two parts.

Thanks @fbiggi! @fiorisi I suppose that some changes are needed on CAD, right?

Anyway, I consider this issue solved.

Hi, @sgiraz all changes to CAD have already been handled by Elio
