Custom Perplexus - "Learning Curve"

This is my 2nd custom-designed perplexus. Note that this is experimental and not intended to be 3D printed unless it's composed of individual parts that can be assembled.

A perplexus is a 3D maze dexterity puzzle in which you navigate the ball, through obstacles by using gravity to your advantage. From inspiration of the Instructables "Design Your Own Perplexus" this was done on SketchUp Pro rather than Autodesk inventor, and the "sweep command" worked with the push/pull, follow me, and align faces commands.

This custom-designed Perplexus "Learning Curve" can fit inside a 95mm^3 plastic cube and uses a >6mm ball bearing (4.76mm ball bearing preferably).

In Learning Curve, There are about 32 obstacles, every part is double-sided and it could be played in reverse. As the name implies, It is moderately difficult as it features the "Rail Pipe", sharp curves, swishy tubes, drops, tight rails, and lots of loops.
