About this 3D model

This holder is for 22 mm polarization cubes (write me if your cube has another size, i'll send you the SLDPRT files). It allows rotating the cube in order to change the power of linearly polarized light. You can rotate it either discretely thanks to the 21 grooves or continuously fixing the position with a screw (see the handle with a nut and the screw at the last picture)
