The file 'Printed Rotational Stage 3D Printer Model' is (STL) file type, size is 2.8MB.
This design is a printed rotational stage capable of a positioning accuracy in the order of 10 micron. Besides 3D printed parts it uses a 6200 and a MR95-zz ball bearings, two springs and M3 bolts with nuts and hot melt inserts. The complete fabrication process is described in an instructable: https://www.instructables.com/Build-a-3D-Printed-Rotational-Platform/
I have a quick demonstration video here: https://youtu.be/pMDN6k8GMak
I also designed various linear stages and a micromanipulator compatible with this model, all the files and building instructions are available here:
