Modular Building System

We are proud to pioneer some of the most significant advances in linear motion being used in the world today! The OpenBuilds V-Slot Modular Building System. OpenBuilds began in 2013 with the simple idea to make an affordable open source system that allows anyone to build anything. Mark Carew designed and developed the first all-in-one modular linear rail that incorporates an internal "V" shaped track paired with self-centering V-Wheels and together they make a endless buildable linear motion system that is smooth, affordable and extraordinarily consistent. Today, V-Slot can be found all over the world from the finest institutions and workshops as well as in machine designs from CNC routers, lasers, 3D printers, linear actuators of all forms, lab equipment as well as camera studios, furniture and the list goes on... We are honored to know of all the businesses that have been started and the dreams that have come true using our system. V-Slot has gone viral because with it you can build anything!
