STACKZ 3D Printed & Carbon Fiber Modular Car Stacking System for 1/10 Track Cars! Fits 1/10 Buggies, Short Course Trucks, and Stadium Trucks - with or without bodies and tires! Great for pit tables and race days This shelf system is available as a Deluxe version to hold 3 cars, or a Standard version for 2 cars. The pieces join together using a high quality 3k Twill Carbon Fiber tube and lock in place using a series of set screws on the back. The upper and lower shelves are completely adjustable and additional shelves can be added to the assembly to hold even more cars! Each base has a set of pass-thru holes which you can use to bolt it to a table for maximum stability, otherwise the Stackz works just fine as a freestanding unit. Great for display, pit tables, race events, storage, garages, and more!
