In colour: https://sketchfab.com/show/nBoUtvueaeWxQlbgA39ewqR54g7 B9 Creator building block with the new resin: 25.4x50x50. White blood cells: 7,8, 12,15. Human egg: 120. Human hair 40,120. The real units listed above are in microns. The new resin for B9Creator that is about to be released allows for even more detailed and smoother prints. I did this model to clarify to myself how small the building block is. I was able to print very well with Spot-A-HT at 25 microns even before Cherry. For reference, my super detailed print of the Eiffel tower was done with a larger building block of 50.8x50x50 microns. http://www.thingiverse.com/thing:113295File units in mm rather than microns and then scaled by 75%. Smallest feature: 1 mm.
