   First try at printing a gradient-index lens based on a variable wall-thickness gyroid lattice with the lattice surface meshes calculated using MATLAB code, then stitched and repaired, imported into Fusion 360, smoothed and then exported as STL into Prusaslicer and printed in PLA on the MK3S+ in the Prusa Enclosure.

     I'll be very interested to see how it performs.

     @jmorris I'm having a few nightmares with material distortion at the moment, but I'm thinking of printing a large Luneburg lens in segments so I can test it more thoroughly. I'm trying to do 100 things at once though, and just wasted four hours trying to fix my old RasPi 3 running dump1090 for an ADSB feed to an aggregator to use in aircraft scatter communications. Turns out the image was SO ancient (wheezy), it was nearly impossible to upgrade. However, it is now shiny and lovely again. Phew!
