This is part 3 of my series on building a laser scanning microscope from an optical pickup unit I salvaged from a defective Blu-ray player. This version fixes some issues I had with the prototype shown in part 2.
In this project, I used 3D prints from PCBWay. Get 10 PCBs for only $5 and 3D Printing starting from $4.98 at https://www.pcbway.com/?from=Doctor Volt
