Marble must be less than 13mm in diameter so that it can fit through all the sections
The Tunnel Pieces should be printed in orientation provided(if one is different change it to match the others) use supports that only touch build plate and the end of the tunnel that prints as a top surface should go into the smaller numbered maze (That is how i did it it should work either way). The tunnels have been shrunk down to 99% of their original size so if it is loose increase their size a little bit
The Mazes all should be printed in orientation provided you may want to use supports but it isn't necessary
To begin put the marble on the slightly raised square on face one and you can begin to finish the ball should be sitting nicely in the raised section on face six
Assembly Instructions:
Put pieces 1 and 2 together with their tunnel (You may want glue) also put "Tunnel 2-3" in with these pieces
Put pieces 3 and 4 together the same as above Also have the “Tunnel 4-5” with these peices
Put pieces 5 and 6 together
Get the pieces that are 3 and 4 and put slide them into the correct spot with 5 and 6.
Finally put 1 and 2 together with the rest it may be hard to get clipped in properly but it will eventually sort itself out
