Ouija Plate and Planchette

grabcad

Design and fabricate a precision-crafted Ouija plate with intricate details, maximizing its scale to occupy the largest possible space on the 3D printing bed. Develop the matching Planchette device with an equal level of sophistication, scaling it up to precisely match the Ouija plate's massive proportions. Place thousands of minuscule glass marbles or tiny copper ball bearings in a perfectly aligned single layer across the entire surface area of the printed piece, acting as a meticulously designed bearing mechanism for smooth and effortless movement under the delicate guidance of the carefully crafted Planchette, reserved solely for personal amusement.
