I love this "Thing" !

I had problems on the Makerbot Mini, Top cover is to small inside diameter.
On the XYZ Duo it prints fine and fits tightly but does fit.

Here is the maze, the answer to the maze and both overlaid as STL's.
I modeled the maze and just the answer so I can emboss them on the top.
Along with a JPG of the maze and answer overlaid.

Makerbot print is black PLA, 190C
XYZ print is white ABS, 210C
