Hi Yi,

I received your 3D-printed mechanical structure (MS), and tried to see how it
matches with the hybrids and T-board from Jianing. I have some questions:

1) the 3D-printed MS for the inner section is not left-right symmetric. Is
this by design or because of the quality of the 3D printing?

2) there are some wedge-shaped concave imprints on the surfaces of the MS.
Are they for hybrid mounting? If so, they seem to not match with the
shape/size of the hybrids. Any comment?

3) How are the hybrids and MS going to be aligned w.r.t. each other during
hybrid mounting? I don't see any holes or alignment marks on the hybrids.

4) How will the T-board be fixed to the MS? Can you show the drawing? Do you
take into account the space that the capacitors and other components on
T-board will take, which may be on the way?

5) How will the Modules be mounted onto the support ring, through 4 screws on
each module? Can you show the drawing?

Thanks,
Zhenyu
