You will require two rollers, a left and right arm, as well as four standard 608 bearings to complete this project. Printing in PETG is highly recommended, as it allows the components to flex slightly, making them easier to snap onto the frame. To ensure a smooth fit, squeeze the longer sides of the arm together, which will help you maneuver the little hump under the frame with ease.
