A simple USB microscope stand for 33mm diameter video microscopes. In the base there are r5x3 magnet slots for e.g. usage with a steel plate.

With the first version you will need to use the ball- attachment fixture that comes with the usb microsopes also one M3 screw and nut to lock the scope to the holder. There is an image taken with a 10 euro video microscope from a 5 euro note where you can see the micro printing features.

I designed a sturdier version of the stand. The joints are to be made with 2 M4 screws and nuts. Probably something like a wing nut might be good.
