This is a print of the greebled cube model used on the Greeble Wikipedia page. I acquired the design by reaching out to Gargaj, the listed creator of the image on Wikipedia, through his website. He told me that he created it using Max Klanky's greeble plugin and he graciously reran the generation code to recreate an almost identical model to that feature in the Wikipedia image. The .fbx file he provided converted to an .stl with some warning flags in the slicer software, but seemed to print accurately enough!
