The OpenFlexure Microscope is a  3D printable microscope, including a precise mechanical stage to move the sample and focus the optics.  There are many different options for the optics, ranging from a webcam lens to a 100x, oil immersion objective. 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 various ( media articles) and a ( paper in Review of Scientific Instruments) (open access).
