STATIC BALL STORAGE MODULE – The newly added ball storage function module stores the track ball steel balls, which not only meets the dynamic entertainment, but also presents another kind of industrial rational aesthetics in the static state.It customizes the “rokr” metal logo nameplate, highlight the polishing process, and match with four pure copper hand screws to make the hard core industrial wind jump on the top.


ROKR Night City Story

At the beginning of the design, for the new model of the “mechanical city track” series, it determined that based on expanding a specific playing method, we should retain the complex mechanical structure of the series, which can act as a tabletop ornament in the process of its static display, so that it can demonstrate the unique industrial property of the trackball itself in. Meanwhile, the first mock exam of the “track of the mechanical city” is to create new ideas for track structure, play experience, and materials to enhance public understanding of “Marble Run” model toys and publicize the aesthetic feeling of industrial order displayed by complex mechanical combinations.
This “night city” takes “future technology” as the creative source and orbital ball as the carrier to show the rigid mechanical structure to the public and feel the order pleasure of steel ball rolling. This product adopts a wood grain dip dyeing process and metal screen printing technology to dye the wood board with high-grade gray-black while retaining the original wood grain, giving it metal texture and an overall profound future style. High permeability acrylic materials are innovatively added to achieve the “suspended” track effect to show more transparent expressiveness. In terms of playing method, the traditional mortise and tenon technology and gear transmission combination are adopted so that the trackball can operate without power. More tracks are added so players can stimulate brainstorming, feel the precision engineering structure, and experience pure mechanical beauty.
Build the set, crank the handle, and watch marbles run crazy down the slopes and twisting turns.

  • Hundreds of suppliers from all over the world provide adaptive parts for a series of products, which are deeply customized to meet the design functions.
  • High precision steady-state laser cutting is adopted, and the process error is controlled within 5um, which is equivalent to 1 / 20 hair diameter.
  • Guarantee that all parts can fully fit and assemble, and each bayonet fits tightly.
  • We choose basswood from the high latitude of the northern cold zone, which is strong and durable.
  • The wood grain is fine and uniform, showing silk luster, layered, wear-resistant, corrosion-resistant and not easy to crack.

Wood grain impregnation x metal screen printing

Rokr Marble Run series has been upgraded and innovated for one year! Break through material restrictions and integrate high permeability acrylic; The volume of the table pendulum can accommodate 2.5m playable tracks; Without electricity, the steel ball can be manipulated by one hand and enter the new era of power in advance… It is built by oneself to stimulate brainstorming, feel the precision engineering structure and experience the pure mechanical beauty.h striking fortress.

Gear drive, infinite cycle

Without electricity, with the tenon and tenon structure and gravity traction, the gears engage with each other to generate force, and the steel ball can be easily operated by hand to enter a new era of power in advance.

Wood grain dip dyeing with metal screen printing

The wood grain dip dyeing process makes the dyed part appear high-grade black gray. The metal screen printing technology allows the wood board to retain the original wood grain and give it metal texture at the same time.
