I don't know if I have copied everything correctly... however:

As a guide:
The blue area I got from Image 3
The orange area I got from Image 2
The green area I got from Image 5
The yellow area I got from Image 6
The dark grey area I got from Image 7
I had to interpret the light grey area from Image 1 and what I had already.
I am really curious as to whether my interpretation of the photos is correct because:
the answer seems not to require more than the top and one edge? Not to mention that there is more than one way to leave start and get to the gate I have marked E1.
EDIT (Post Solve by Kyle Williamson
Just as a side note, there are many ways of solving mazes (wall-hugging etc) though I find that I get lost if I try to tackle the whole of a "wrapping" maze such as this one.
Not that you have asked for one, but my mechanism for solving this kind of maze would be:
- (If you don't have it - Draw a map!)
- Label all of your "transfer points" on each map piece uniquely using the same marker on both sides.
- Start at the Exit and list all the transfer points that you could reach without going through one.
- Cross off any that lead to a dead end
- If they aren't a dead end, list the new transfer points you can get to from this point that aren't earlier in your chain.
- Continue until one transfer point is Start.
Not the most elegant process, but it works.
