Motorized optical filter stage

Postby felipe » Wed Dec 18, 2019 3:55 pm

This a motorized stage to move an optical filter inside a microscope. The project has been designed using FreeCAD Python scripts, so it is fully parametric.

The following parts can be easily 3D-printed without supports: Image

The design is available here:
which includes more pictures, the Python source code, the generated FreeCAD and STL files, and a small tutorial.

Initially, we started the design using OpenSCAD, and the files are also available:

We have compared the design process using FreeCAD Python scripts and OpenSCAD and have shared the results here:

A very impressive and thorough article on PLOS.
I wonder if most forummers has overlooked this.
There should be a lot of potential for Freecad to references to this article. Not as a comparison whit another cad program but for the in dept explanation of features.
