The actual building of this didn't take too much time- waiting for paint/glue to dry between steps was the longest thing.
Step 1: Materials
Strips cut from junk mail cards make the 'channels' of the maze.
The plastic for the cover is from some packaging I saved (yes, I do have a lot of junk around- no side eye please :-} ).
usual craft supplies- pencil, scissors, etc.
Step 2: Step 1
After making an outline of the box, I drew a copy of the chosen maze. Counting the number of rings needed, I made a paper template and took the measurements from there. The reason for this step is because the sides of the box prevented my ruler from laying flat and getting an accurate measure. On a strip of paper that fit inside the box I marked the circles on the paper and transferred them to the box. Then I redrew the maze inside the box and outlined it for better visibility.
The pix below are worth a thousand words of explaining!
