Maze 18x21

I wanted a maze that looked nice, and was easy for most people to work. The basic maze was created using Maze.scad. It can be downloaded at: ( https://www.thingiverse.com/thing:801913/files)

If you want to make a new maze, or adjust the size of this one, the parameters I used are listed below. The frame was designed using Fusion 360 (Maze_Frame.f3d file included here.)

The maze is 222 x 194 x 9.6 mm, and the frame is 242.8 x 204.8 x 12.4.

The ball channel is 8 mm wide, and I used a 7.63 mm diameter steel ball.

I cut a 0.8 mm sheet of plastic to the size of the basic maze, and drilled to small holes for the steel ball.

Parameters for the Maze.scad program are:
 

• width = 21
• height = 18
• type = Sidewinder
• direction_bias = 8
• wall height = 8
• inside wall thickness = 1.6
• outside wall thickness = 10
• include an entrance = 0 (no entrance)
• base thickness = 1.6
• random seed = 0

Parameters used to print the maze:

• layer height = 0.2
• Parameters = 2
• Solid layers: top = 6, bottom = 4
• Avoid crossing perimeters: checked
• Seam position = Aligned
• Infill: 15% (Gyroid)

     Note: I did a color change at 1.8 mm (black bottom, green top)

Parameters used to print the frame:

• Layer height = 0.2
• Parameters = 2
• Solid layers: top = 5, bottom = 6
• Seam position = Aligned
• Infill: 15% (Gyroid)
• Brim type: Inner brim only (7 mm)
• Skirt loops: 0

     Note about color change: Since the frame is printed upside down, I started with the top color green, and the color was changed to black at 11 mm to match the black bottom of the maze.
