Maze Can

Give the kids something fun to open. This is a Maze Can that's roughly 3 inches in diameter and about 1.25 inches high. There are three tabs inside the lid that match up with identical maze pathways on the core, and there are three dimples on the outside of the lid to show where those tabs are inside. It should be printed out in PLA for extra rigidity. If you use nylon, PETG or some other flexible filament, the lid will squeeze and it won't fit properly. It's highly recommended that you slow down your outer perimeter layers when printing this design. Set them to print very slowly (20-30 mm/s) and you can go up to 70 mm/s for the inside fill. If you print too fast, the maze pattern gets a little exaggerated and swells outwards, requiring a lot of sanding on the outside diameter of the core to get the cap to fit properly. When I printed both pieces at 70 mm/s, I needed to do a lot of sanding to clean up the outside diameter of the core and the maze pathways. But when I slowed down the outer perimeter print speed to 25 mm/s, there was hardly any cleanup required and the tabs moved through the paths just fine. The cap fit over the core with no problems. Be prepared to sand off any abnormalities on the sides. It's also a good idea to put some lubricant like Vaseline in the maze track since PLA doesn't slide well on itself. Making mating parts work on every different printer can be tough, but slower speeds always help when parts have to fit together perfectly. I filled them with candy and gave them to my grandkids to play with - they loved them! Each one had its own color. Check out the included documentation for maze layout details.
