A Modular Marble Run Kit for 16mm Glass Marbles, Perfect for Expansion. Specifications include: Each module measures 30mm high with 18mm diameter channels. The straight sections are 26mm wide but can vary slightly from piece to piece. The inlet and outlet diameters are also 26mm, making it ideal to maintain consistency. On top of each section is a distinctive prominence that encircles the marble channel, measuring 1.3mm high and 21.2mm in diameter. This fits neatly into a socket at the bottom of each module, which measures 21.6mm in diameter and 1.5mm deep. The supports have a top prominence of 9.6mm diameter and 4.5mm height, fitting snugly into a socket that is 10mm in diameter and 4.5mm deep, with a domed roof for added tolerance and printing flexibility. All designs were created using Tinkercad. Suggestions or compatible designs are welcome - thank you! Watch the video at https://youtu.be/Ho8QCIx14d8 to see how it works. Notice in the video that the top piece is slightly loose where it fits onto the swirl bowl, which warped a little during printing. Normally, the pieces fit together quite securely.
