Marble Maze Kit - Countdown Calendar Piece

This is an additional piece to my original marble maze kit (found on my account) that functions as a countdown calendar! Drop one marble a day and it will show the number of days left. I have also attached a count-up version if preferred.

Assembly is fairly easy, with an image attached for reference, just slide on the pieces and constrain with 3 clips. If there are any issues, let me know!
