This is a flat printed Cable Chain that is assembled into the final shape. This gives you a stronger, cleaner part that will move smoothly.
0.2 initial layer, 0.1 layers, 0.2 Nozzle.
This has been tested with PLA and PETG. I use Knipex pliers to squeeze the parts together because the jaws move in parallel. I also tried with long nose pliers but it is much more difficult. I found that PLA can be squeaky as the faces rub together, so my recommendation is to use PETG. It is stronger and silent.
