Wire chain for Sunhokey Prusa i4

thingiverse

This custom cable chain is designed specifically for Sunhokey Prusa i4 printers, based on a modified version of A.N.Onymous's original link design found here: https://www.thingiverse.com/thing:666118 Several key changes have been made to the original design to enhance overall performance. The first notable modification is the lengthening of the link shafts to provide a more stable and solid chain structure. To further improve print quality, small support bars have been added underneath each shaft end. However, it's essential to remove these supports before assembling the chain. In addition, the first ten links out of twenty-three have been tweaked to exhibit stronger bending properties. This adjustment is necessary due to the proximity of the print head to the acrylic frame when positioned in the right upper location. To complete the assembly, two end links were created. The initial link is attached to the bottom of the extruder stepper motor using glue, while the final link is secured to the right side of the acrylic plate adjacent to the frame. A 10x10mm notch was carefully crafted on the right side of the acrylic plate to facilitate easy detachment of the wire chain if required. This thoughtful design consideration ensures hassle-free maintenance and repairs. For users who prefer to make adjustments, SketchUp sources are available for reference and customization.
