Desk/workbench mount for the microscope camera 36Mpix with zoom x180 optics

A holder above the worktop for a microscope camera from aliexpress, described as 36Mpix (it will probably fit others where the lens is of this type, on C-mount).
camera bought here: https://www.aliexpress.com/item/32827892872.html plus a zooming lens https://www.aliexpress.com/item/32470898806.html x0.5 (because I don't want to see bacteria, only smd components)

The lens has diameters:
- bottom ring on the camera body 43mm
- lens right when screwed into the 39mm camera
- lens retaining ring (biggest) 57mm
- lens under the snap ring 49.5mm (thickness of the notched rotating focusing element - it is of the same diameter, so during assembly the handle will pass through the bottom without any problem)

Using V-slot profiles and rollers from old 3D printers - I assembled a movable X Y Z camera mount. Screwed to the cabinet above the worktop, it allows me to set the camera - microscope directly above the repaired equipment, without interfering with work. And when it's not needed - put it aside.
The only problem was the stable mounting of the camera itself with the lens, so that it would not vibrate (at x180 magnification, any vibrations are very strongly transferred to the image, blurring it) and at the same time - so that the cables would not collide with the profiles.

I designed such a handle for 2020 aluminium profiles 
mounting screws - M5 x 10 with T-nut
tightening srews - M3 x 12 or 16, with simple m3 nut (my camera dont need to be tightened here - is strong enough without it). 

By the way, there is also a small box for switches (18mm x 7mm, popular small rocker switches) - the camera itself, lighting, and a fan extracting smoke from the soldering iron.
