This model is a compact 3-tier roulette game using 11mm steel balls. Like the standard version, it is based on a mechanism well known in Japanese pachinko machines, and became especially famous through the "Numa Pachinko" scene in the anime Kaiji. Drop a ball into the inlet at the top, and the lottery begins as it spirals down from the upper tier. If the ball lands in a winning hole marked with a red ring, it advances to the next tier below. If it lands in a losing hole, it is returned through the opening at the bottom of that tier. If the ball makes it all the way to the 3rd tier and wins, it is sorted into the winning lane on the right side. The winning probability is 1/2 on each tier, giving a theoretical probability of winning all the way through of 1/8. The disc diameter is approximately 6cm and the total height is approximately 14cm.

I would love to share it with the world, but due to shipping costs, I am only able to fulfill physical orders within Japan. I believe selling this unique niche toy is one of the most effective ways to see quick and tangible results in your sales revenue. For the first time, I am offering a commercial print-and-sell license exclusively to sellers outside of Japan. Join my membership and start selling today!

Print Settings Print settings are pre-configured in the included 3MF file for Bambu Studio — simply open and print as-is. Settings are optimized for PLA. If you use a different material, adjust the slicer settings as needed. Disc: 0.12mm layer height Post: 0.20mm layer height Infill pattern: Gyroid (recommended for the smoothest surface finish) Several slits of approximately 0.5mm are incorporated into the back of the post and the underside of the base. These are designed to prevent warping caused by filament shrinkage during printing.

Assembly Assembly requires the following additional hardware (not included): M3 × 6mm screws × 6 M3 hex nuts × 6 Cushion pad × 1 — to absorb the impact of losing balls at the bottom tier. A gel cushion of approximately 10mm diameter is recommended. If you prefer a different material, feel free to substitute. If no cushion is used, note that there is a hole at the mounting position — please fill it using your preferred method. Use M3 screws and nuts to connect the discs to the post. The package also includes O-ring data to mark the winning holes on each disc. While the rings look identical, each one is specifically designed to fit its corresponding disc. Please check the file names carefully and attach the correct ring to the matching disc using a small amount of adhesive. 2-Hole Ring → disc with 2 holes
