I am at a loss trying to figure out what this tool is, hopefully this is being asked in the right place.
The images are screen shots from a video, hopefully they are enough.
It is quite small, perhaps about 15cm on each side. It appears to do small position adjustments using the 2 silver dials on each side. The small oval plate on top I think tilts.
The tool is being used in the video to screen print small items where positioning is critical.
I hope this is enough information.
