Marble Maze Cube (simple) - Plans

Time for another plans post! Here is a construction manual with plans for a very simple version of my marble maze cube. The idea is a three-dimensional, hidden maze through which one has to guide a marble or steel ball.
This cube contains one of the most simple mazes possible, where each "floor" can be solved alone to get to the next one. More complicated versions contain more changes between the floors.
Be sure to watch the time-lapse video of the simple construction process below before reading the manual! A 3D stereoscopic version of the video is available here.

DIY no-budget stereo goggles

Have you ever asked yourself how to view all these stereoscopic 3D photographs, films and artwork out there without expensive equipment?
Or are you a stereoscopy enthusiast, but your friends cannot view cross-eyed?
Made from a CD cover and filled with water, these glasses are a costless, easy to build solution. The viewing experience is very pleasant and the glasses can be used for a wide range of media sizes.

I built the goggles following a very comprehensible tutorial on vrtifacts.com. The construction is very simple and doesn't require much more than a CD cover and all-purpose glue.
