Building a Micrometer-Level Displacement Sensor with 3D Printed Parts

According to a recent Hackaday post by Aaron Beckendorf, 3D printing has made it possible to build precision measurement tools at home. His micrometer-level displacement sensor uses printed plastic and off-the-shelf mechanical components to achieve accuracy that rivals professional instruments. For machinists and DIY engineers working at the limits of precision, it's a reminder that the tools enabling micro-scale accuracy are becoming increasingly accessible.
