Walls maze game (similar to Quoridor)

This is my original 3d design based in the Quoridor game, but with very fun variants!

Every turn, each player places a wall and then moves one box in any direction (except diagonally). The first person to reach the other end wins!
-Exceptions: A wall can't be placed if there is no route of scape left for any of the players.

The difference from the Quoridor game are the new L shaped walls and the three box long walls (a complete barricade).

Also, the board is at the same time a box in which all the game is kept (im really proud of this simple but great functioning mechanism)

For playing you have to print:
-The board
-One lenght walls : 20
-L shaped walls: 3
-Two lenght walls: 3
-Three lenght walls: 1
-Token: 1

Dont get scared by the numbers, printing the walls only takes around an hour for each team colour (2), though the printing of the board takes 12h (but you only have to print one of these!).
