The author remixed this model.
I hard a hard time getting the clamps for Simon_03's awesome cable chain to attach to the base of my printer, so I removed the inner beaks from them. They now attach easily while still having a solid grip.
I'm an absolute novice with 3D design, and anyone who knows more about Fusion360 than a 10 minute YouTube tutorial can teach will probably be able to do a better job, but the imperfections the remix introduced are hidden when the clamps are attached.
