A simple solution to hold the electric microscope tight when using. Its original adhesive suction pad is not strong enough to hold the weight of the microscope.
The hight is not adjustable, but it doesn't really matter as the zoom level is good for inspecting and soldering circuit boards with SMD components. You can however, print the vertical post with some Z scaling to your like.
The parts should fit snug together. If not, use M3 screws to secure.
Height adjustable version made of CNC aluminum cost about 25 USD on Aliexpress.
