We are currently working on a new design for our dual-camera microscope head (see previous log entry), and accompanying that we are also designing a new stand. While the previous design of the stand is nice and sturdy, it involves a bit of metal work, what might scare away some of the electronics nerds. The new one is 3D printed. It's base is hollow and can be filled with stuff to give it the necessary weight (we used lead shot, but some metal screws or nuts should work nicely too). The connection between the base and the camera head is made with a cheap "magic arm" (search for "magic arm 11 inch" in favorite online shop), allowing for easy repositioning of the cameras while still providing good rigidity. 

The magic arm has the typical 1/4" screws on both ends (used everywhere in photo equipment). The lower one sits in a matching brass insert to hold it firmly, while the upper one still waits for the new camera head to be finished...
