Frame Cable Runner for i3 Prusa

thingiverse

A compact runner fits snugly over the Prusa i3's 6mm metal frame, safeguarding its electrical cables with precision bearings. Specifically designed for this task, these small but vital components measure as follows: Bearings details: * Outer Diameter: exactly 12mm. * Inner Diameter: 4mm precisely measured. * Depth: a modest 4mm to ensure they don't encroach upon surrounding space. I'm convinced that these are indeed 604-ZZ bearings. While it would be beneficial for the bearing's thickness, its depth, to be slightly increased, the outer diameter's tolerance is remarkably precise. Printing Parameters: * Rafts aren't a concern here; feel free to ignore this option. * Supports are not needed in this particular project. * The printing resolution should be set at 0.2 mm for optimal results. * Infill percentage is crucial; I recommend a density of 20% to ensure stability and durability.
