Introduction: Circular Maze With Living Hinge Walls
A wooden maze with straight walls is easy to build. You just use rectangles for walls and make all the turns 90 degrees. You can easily cut these out on a table saw. But what if you want a maze with curved walls? How do you bend the wood?
One way to do this is with living hinges. A living hinge is a pattern of parallel cuts in a piece of wood that make it flexible. In this Instructable I'm going to show how I make a circular maze with living hinge walls.
Step 1: Cut Your Parts
To create the maze I used a combination of Autodesk's Fusion 360 and Adobe Illustrator. I used a laser cutter to cut out the parts. I have attached .svg and .pdf versions of the files to this Instructable.
You can see from the photo how a piece of wood goes from inflexible to flexible with the addition of the living hinge cuts.
Step 2: Glue Maze Pattern to Base
I cut 2 circles. One with the design of the maze cut out of it and one plain one for a base. Glue them together to form the floor of the maze.
Step 3: And in the Living Hinge Walls
In Fusion 360 I was able to select a section of a wall and measure the length of the curve. This allowed me to figure out how long of a wall cut for it. Match the wall pieces in the attached files to each of the curves in the maze. My laser wasn't able to cut the outside wall as one piece (to big) so I broke it into 2 pieces.
Add some glue to the maze grooves in the floor of the maze and then press the living hinge walls into into the groove. The living hinge will also stretch as well as curve so you can pull it if you need to fill in bit of a curve. I had to trim a few pieces with a knife to make them fit.
Step 4: Add the End Caps
Where a section of the maze comes to a dead end you will need to add an end cap. Since this is just a straight wall you don't need to add a living hinge cut to these. You can just use a rectangle to fill it in.
You maze is now finished. I added a 1/2" wood ball to mine to roll around in it.
