“A 3D Printable microscope and translation stage. The trick of making a microscope out of a webcam has been around for a little while, and produces good results. However, getting a nice mechanical stage to focus the microscope and move around on the sample is tricky. This project is a 3D printable design that enables very fine (sub-micron) mechanical positioning of the sample and the lens, with surprisingly good mechanical stability. It’s discussed in a paper in Review of Scientific Instruments (open access).”
