About this 3D model

Double Sided Marble Maze when I was kid I loved mazes. For this project you will need to buy additional one steel ball 6mm. You can print transparent cover using transparent resin or cut plexi glass. Before give ready printed toys think "This toy is safe for my child?" Please is really important. Please sand surface if painting use not toxic paints. Use got glue to join parts. Don't use this very toxic glues. Play nice and be safe.
