I've reached the 6000 POB tokens staked point so here's a post about 3D printing a brain. More specifically a brain keychain from Thingiverse posted by user HgArgen under a Creative Commons CC-BY license. HgArgen's design is a remix of the "I Think" brain model by Thingiverse user hyla.

There are two files for the design available; Brain_keychain_1.stl and Brain_keychain_2.stl. According to my slicer software each file takes roughly an hour to print and almost 2.2 meters of filament. I printed from the Brain_keychain_1.stl file.

I don't plan to use this as my own personal keychain. The bottom is a little rough after the supports are removed. I printed with a 20% infill. If I intended to use this as an everyday item to carry around in my pocket the infill would have been closer to 100%.
