Visible Infill And Filament Sample

Wanted a small easy piece to print to explain and show infill to someone else, and get some filament sample swatches in the process.  

Not much to the models, the magic is in Cura(I am assuming PrusaSlicer or MatterControl can do this too). Stack the two with the Infill model 1mm off the bed, and using a seperate mesh for the infill, print it with 0mm walls, top and bottom, and choose whatever infill you want, and %age. 

Do whatever for the frame, I used a fake vase mode at 0.8mm walls and no top to make it fast and easy.  1mm floor so the Infill model isn't floating in thin air over it.
