Rush hour logical game with cars

Rush hour rules are easy. Clear the way for the red car to be able to leave the parking lot. Cars can move only forward/backward, no lifting the cars!

Printing:

• Depending on the challenge difficulty, you'll need to print up to 4 trucks and 12 small cars.  One of the small cars must be printed in red.
• Parking lot can be printed using filament color change in a layer to highlight lanes and arrows
• If you want the room to storage challenge cards, you can print attached container.
• No supports needed.

Other hardware:

• Besides filament, you'll also need 72 pcs of cylindrical neodymium magnets 5x1 mm (diameter x height). It is not mandatory, but it's much more comfortable to play with magnetic cars. Use supper glue to attach magnets to place.
• For container, you'll need 8 pcs of neodymium magnets 8x3 mm.

You can generate challenges using online generator, for example here. If you decide to print them, recommended maximum card size is 125x125 mm. I attached several example challenges.

Future outlook: I might build a travel box.
