Cube Maze

This is a fairly simple maze cube. Get the ball from the Start to the opposite side of the cube, where it will fall into the center, taking it back to the start.

It uses a 7/16" ~ 11mm ball bearing. I designed it around that exact size. The wall thickness between two paths is .8mm. If you decrease the size of the model, you will end up with less than 2 layers which might decrease the integrity of the maze. You should be OK increasing the size, but the maze walls may not fuse in the middle using 2 layers. I've included my Simplify3d factory files. The one labeled TOP is for the top piece only. The other one is for all the other sides. This will give you the best settings for layers and infill type. Since I'm using a e3d Titan, which is direct drive, you'll want to change settings such as retraction to match your setup. You'll need to print 2 each of the End Caps and the Trap Doors. It works best to print the end caps with colors that will make it easier to identify the start and the end of the maze.

Post-Printing
Get a small paper clip and straighten it out. It should be able to fit into the hole of the trap doors and move with no resistance. Looking at the bottom side of the maze, you'll see where the doors go. Cut the paper clip so they are slightly shorter than the groves they will go in. Snap each door into place with the slight hump facing up. You may need to use pliers and a screw driver to get it to go in. Make sure they move freely before you assemble the rest of the cube. These door keep people from rolling the ball into the end of the maze. Give all the pieces a test assembly. You wan't to make sure everything will go together correctly before you start gluing. Have a handful of rubber bands ready. Set the top and bottom pieces aside. Take the other 4, lay them in order on the table. Place some glue in the areas that look like they are going to touch piece next to it when put together. You don't want to get any glue into the ball path. Leave one side laying flat and attach the 2 piece on either side of it. The last piece should go on top. While holding all the pieces together, flip it so the open spaces are now on the top and bottom. Wrap several rubber bands around it to keep it together Put some glue on the walls facing up (but not where the ball will roll) and put the corresponding piece in place. Flip it over and do the same for the last side. Wrap some more rubber band around, to hold the top and bottom in place. After the glue has dried, add the end caps Do the one on the bottom first Make sure you drop the ball in before you add the one on the top. Let that dry and you're good to go.
