Now I have also built myself a "holographic display". The two plates were made with the 3d printer, I cut the side parts out of 2 CD covers. Drawn in Fusion 360, printed on the JGAurora A5X in GlitterPLA "Platinum Silver" from Redline. Temp.: 215/55
I am more than surprised by the result. I didn't think the "hologram" would be so clear and sharp.
