Zoom H1 shock mount

Designed for my friend, who use Zoom H1 mounted by 1/4 hot shoe to his Sony A6000.
Thickness and positioning of mounting hole refers to Sony A6000 body, but it should work well with any camera or tripod.
I made two verisions of that mount:
-with build up spacer (wall thickness near mounting hole 10,5 mm),
-without spacer (wall thickness near mounting hole 4 mm),
and spacer.
I forgot to thicken the wall in my previous design, so I'm adding it too.
