This design is an orthogonal printed linear stage with a positioning accuracy of up to 10 micrometers. Apart from the 3D-printed parts, it only uses a 2mm metal rod, a 40mm spring, and a 55mm M3 bolt with a nut and a washer. The complete manufacturing process is described in the following instructions:https://www.instructables.com/Build-a-3D-Printed-Linear-Stage/

I have also designed other linear platforms and micro-manipulators compatible with this model. All the files and construction instructions can be found here:
