AD407 microscope Rotating PCB Holder version2

[EN] Andonstar 407 microscope PCB Holder.
I bought the new Andonstar 407 microscope for professional purposes related to PCB design, soldering and inspection, and designed a PCB holder that worked well for some time. You can download it at: https://www.thingiverse.com/thing:4128609
This previous PCB holder could rotate, but I found out that it was difficult to move the PCB up-down or left-right, and designed this version so the PCB can be moved in any direction or rotate, while firmly attached without the use of any hand.
This new holder uses a magnet to keep the holder attached to a metallic surface over the base of the microscope which, unfortunately, is not magnetic.
You need:
- 2 M3 nuts
- 1 low profile magnet from an old Hard Drive, or a neodimium magnet.
- 1 rubber band.
- A 120mm x 120mm or larger flat piece of metal.
- Glue.


Follow these steps to build the holder:
1.- cut the metallic surface to fit or exceed the base of the microscope.
2.- Drill two M3 holes 46
