Almost Impossible Maze Gift Tube

Do you want to give someone a gift, but also want to make them really work for it? This is the item for you!

The interior of the tube is about 55.5mm, so it's just big enough for a standard gift card.

This is not your typical puzzle tube. This one is nearly impossible because you can't even see the maze. Unlike other tubes, the maze is on the inside of the lid instead of the outside of the tube so you have no visual references when trying solving the maze. I've also added various dead-ends and loops in the maze to make it harder.

The provided tube print profile gives a very subtle hint to show where the nub that travels the maze is. It is sliced in such a way that the seam lines up with the nub. This may be helpful for you as you try to put the lid on, but it won't really help anyone solve it. Speaking of a little help getting it put together, here's the maze with a few routes to the goal. This will hopefully be helpful as you try to put the lid on. Note the paths that leave the edge of the maze actually connect since the maze is wrapped around the lid.

Good luck!

Printing Tips

Don't scale!  Scaling down doesn't work.  The space between the maze and the inner core becomes too big and you're able to just pull the lid on and off.

If you're not using the provided print profile, no more than 5% infill (I used grid) and the standard two walls will work out just fine.

Tolerance between the maze and the lid are tight at just 0.1mm on each side, but in my testing it works very well.
