Maze 54x44 square cells, center start

I present to you a 54x44 square cells, orthogonal maze.
You have to start from center and the exit is at the bottom.
The maze is a little bit hard to solve, but the time to solve it is worth it.

The total maze size is 240x200x11mm.
There is 5mm height to put a glass or a Plexiglas cover.
It is made to be use with a 3mm metal ball.

You can print it in one color, or multiple color (I used 2 colors, I provide a .bgcode with two filament changes and the maze can be printed in 3 colors).

Very important: the filament must be dry, otherwise you will have a lot of stringing.
