I printed these blocks using my Prusa i3 MK3. .4mm nozzle and .15mm layer height. It might be fun to try printing these using the .25mm nozzle I have and a lower layer height. To be honest, while the layering is visible in this photo it would be MUCH less obvious at normal viewing distance.

I played around a bit with trying to get the right color on the blocks. I first hit them with gray primer and then an A/I wash. That was too dark so I made a slurry of Acrylic ‘Linen’ and water and dunked the blocks. I just HAD to see how they looked so posed this little pic.
