Gravitrax Junior Randomize Tower

Description:
Introducing the Randomize Tower, a unique vertical addition to your Gravitrax Junior marble set! This tower stands approximately 85mm tall and adds an exciting element of unpredictability to your marble runs. With one input entry at the top level and two outlets at the bottom, marbles exit the tower randomly through one of the two paths.

This design introduces a "new dimension" to your marble builds:

• You now need to plan and construct three tracks: one for the input and two separate exit paths.
• It encourages vertical gameplay, making it an ideal complement for riser sets available on Maker World.

A small hole for the decorations has been added at the top.

Printing Instructions:

• Position: Print the tower in a lying orientation for optimal results.
• Supports: Use tree supports placed only on the print bed. Minimal supports are required this way, and the print remains efficient.
• Infill: I used 5% gyroid infill.
• Top/Bottom Layers: Concentric pattern for improved aesthetics and stability.

Dimensions and Key Measurements:

Here are the core measurements used in the design, including insights from the reference sketch:

• Outer shape radius: 12mm
• Inset/Inner radius: 9mm
• Outer paralell distance: 59.3mm
• Inner paralell distance: 44.5mm
• Inset depth: 3mm
• Track width: 24mm
• Decoration Inset Hole: 6.8mm
• Usual track depth: 4.5mm

Hope this helps some to generate cool pieces!
