Considering a 3D printed slot car chassis? The real question isn’t “cool factor”—it’s stiffness, alignment, weight, and whether it holds up track time the way a proper build should.

If you’re dialing in performance or chasing a chassis that you can’t find off the shelf, this one’s worth your attention.

News about NationalRacers3D Porsche 909 Bergspyder – Last 4 Units Available

Today, the final 4 units of this exclusive model are once again available for sale.

Only 12 units were produced, each individually numbered and certified. The units currently available carry serial numbers 8, 9, 11, and 12.

At this moment, we are releasing the last units that had been reserved for clients in the United States. However, by mutual agreement, these reservations were cancelled today due to the significant increase in shipping costs.

These reservations had been active even before the launch of this exclusive model. Following the implementation of new tariff conditions affecting export shipments to the United States, and due to the substantial increase in costs associated with customs procedures and transportation, some clients requested that we wait for possible clarification and revision of shipping conditions and costs to that destination. As a result, the reservations remained active until now.

At present, after all this time, there are still no signs of improvement. Therefore, considering the current shipping procedures to the United States and the associated increases in customs processing costs, carrier fees, tariffs, and related charges, the units previously reserved for customers in the United States are now available to interested buyers.
