Portal 2 refraction cube (Discouragement Redirection Cube)

thingiverse

*DISCLAIMER* First off - this looks a LOT cooler in real life than my sucky pictures. It's also rather small, so imperfections are more visible! :) *OVERVIEW* This is a simple frame that you build around a marble to make it look like the laser refraction cubes in Portal (Discouragement Redirection Cube). It comprises 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 best effect! *NOTE* It has been designed to fit neatly around a marble that has a largest diameter of 16.5mm, so if your marble varies from this in size, simply measure the largest diameter on your marble, then scale the items before printing by (YourMarbleDiameterInMM*100/16.5) percent.
