Comments
_______________________________________
This is my first scan try-out of my newborn: the "MICROscanR" - a 3D focus-stacking robot, aimed at creating 3DGS of tiny objects
Object size range MICROscanR: (1x1x1 mm - 250x250x340 mm).
Unfortunately this May-beetle had been laying around for two months, because I was still finishing my build of the MICROscanR. During that time it has picked up some mold here and there (those are these white threads and the fluff you see). Perhaps I will redo this one sometime.
