Portal 2 refraction cube (Discouragement Redirection Cube)

thingiverse

DISCLAIMER: First off - my pictures don't do it justice: it looks a whole lot cooler in real life! It's also rather small, so any imperfections are more noticeable! :) OVERVIEW: This is a straightforward frame that you build around a marble to make it resemble the laser refraction cubes from Portal (Discouragement Redirection Cube). It consists of 6 faces with 8 corner pieces that all get glued together. All parts are designed and laid out to print without supports. TIP: When printing the sides, take note of how your slicer has sliced the first layer - I used 2 perimeters and concentric infill to get the best result. Use a clear green marble for the most striking effect! NOTE: It's been designed to fit neatly around a marble with a largest diameter of 16.5mm, so if your marble varies in size, simply measure its largest diameter, then scale the items before printing by (Your Marble Diameter In MM *100/16.5) percent.
