Geeetech Aluminium X Axis Cable Chain

thingiverse

Update 31 Aug 2016 The design flaw in the X Endstop model has been identified as a defect inherited from its original design. When printing tall objects, this support piece collides with the underside of the top bracket that holds the smooth & threaded rod. Consequently, you will not achieve the full 180 mm Z height - instead, you will lose about 130 to 140 mm before the X axis stops abruptly. I redesigned the piece and relocated it to the top of the mentioned bracket. The new design is fixed as shown in the Sketchup model and requires only one M3 screw for secure tightening. To assemble the chain pieces, you will need a total of approximately 18 units. Initially, I found these cable chain mounts for my printer by gsimpson2g but discovered that they required threading wires and additional modifications involving unscrewing all the wires for re-threading. Later, I came across this open-ended chain closed with a clip-on "lid" by sadkins1981. This design was ideal for me, but I had to make some modifications as the fittings were different from my mounts. I imported and remixed the model, widening it slightly to accommodate more wires if needed. The result worked fine, although the chain formed a semicircle vertically. After seeing this video - https://www.youtube.com/watch?v=9A7eHEwHVE4, I decided that further modifications were necessary to achieve horizontal chain placement instead of vertical alignment. This model is the outcome of extensive printing and testing, with the chain now "almost horizontal" and functioning beautifully. Print Settings Printer: Geeetech Full Metal Aluminum Rafts: No Supports: Yes Resolution: 0.2 Infill: 25 - 30% Notes: Proper object placement during printing is crucial for smooth rotation of parts. Print them as posted to avoid issues, and consider higher infill percentages for the two mounts to strengthen them. The main cable does not require high infill levels. You will need approximately 15 to 16 chain and "lid" units to achieve a proper length. Post-Printing Some cleanup is necessary, along with filing to ensure the chain fits as per picture #2 due to tight tolerances. Follow the video posted above for guidance on releasing the chain after printing. Simply fit the chain without lids, slot in the wires, and then clip on the lids. This process is easy and effortless.
