The Aperture Science Cube from the video game Portal.
Contains 4 .stl files. Three full cubes, one with Aperture Science logo, one Companion Cube (with the heart logo) and a blank template without a logo. The fourth file contains both the Science and Companion cubes, cut in half (to be glued) to print without support.
Some of my very first models, made using TinkerCAD and some image to .svg online converter.
No .gcode as I designed and printed this before I upgraded to an original Prusa Mk3 or Mk3/S.
