Light screening cone

As part of the research of the [ChIP lab](http://chiplab.chem.polimi.it) on Luminescent Solar Concentrators (LSCs), we needed something to improve our measurements. Indeed, light from the solar simulator was coming directly to the optical fiber, without passing through the LSC. We hence needed something to cover both the edge of the LSC and the cosine corrector to which the optical fiber is linked. These two 3D-printed cones, designed by [Andrea](https://www.thingiverse.com/andremaker/about), answered our problems.
