400mm Length Magnetic Ball Joints Carbon Fiber and Delrin Rods Arms for Delta Kossel 3D Printer

I purchased these about a month ago directly from the seller (at the same price). They are extremely high quality. Moreover, they were shipped to me quickly, which is significant since they are custom made.I have seen a significant improvement in my prints. I have 500 hours on them now with no signs of wear (I use conformable PTFE tape (available here on Amazon) instead of traditional lubricants.If you have had your Delta printer for a while and noticed that the prints are not as good as they were when it was new a potential culprit is loose fisheye ends because the movements of the printhead, especially during infill, can be pretty violent resulting in significant wear. This wear causes the joint to loosen over time. Some use rubber bands or springs to tension the joints. That works for a while, but it actually causes more damage to the joints.In my experience, mag ball rods/ends do not snuffer from this type of wear.
