It seems silly to make this derivative it's own thing but it was a required change to enable the OpenSCAD mazes to be printed with the "spiralize the outer contour" option checked under the Expert Settings in Cura (or similar mode in other slicers). I added a cylinder to the object to make it solid... you are then free to print only the single outer wall. I decided that I had to try this after printing the lid to the maze with the spiralize option (see object http://www.thingiverse.com/thing:1988521).

You might have to play with the measurements/scale slightly depending on your printer and settings. I printed the mazes and lids at 100% scale across the board as long as the lid and maze are made of the same material. If you are mixing/matching materials then you will have to scale of the items slightly up/down up to 2% depending on the material.

The example prints photographed above have the bottom 13mm cut off of them in Cura's settings and 3mm "solid" bottoms. This works well with the spiralized lids but doesn't give very much to grip if using the original lids.

I modified 10 of the mazes from the customizable openscad maze but you can paste in your own or generate a random one (see source object for link).
