Parameterized cable chain

thingiverse

There appears to be a multitude of cable chains available on Thingiverse, unfortunately the majority are only offered in STL format, rendering them unusable without additional software. Many designs lack critical features, such as support structures, making it difficult to print them successfully. Those that do provide design files often require tools beyond my capabilities, while others fail to specify essential details like bend radius. A cable chain's primary function is to regulate the flexing of cables, preventing metal fatigue and breakage by limiting the bend radius to a safe value. However, if this critical information is not provided by the manufacturer, it suggests that the cable is only intended for static applications, making it unsuitable for dynamic systems like robot arms. It appears that designing cable chains has become a popular trend, and I require such a component for my project. Consequently, I have decided to design one myself. My primary objectives are as follows: 1. The design should be printable on a Taz 6 without any post-print modifications or cleanup. 2. The channel width and height must be adjustable. 3. The minimum bend radius needs to be adjustable. 4. No fasteners or clips should be required to hold the wires in place. 5. Any link can serve as an end piece, eliminating the need for specialized components. The settings within the attached design files are tailored to work with a specific cable, namely the HF539-10 from Digikey, which boasts an impressive 400000 cycles at a bend radius of 1/2". I have adjusted the radius to 1" in my design, ensuring that the plastic cable chain parts will likely outlast the cable itself.
