So, I just got our 3D20 for our school district. I was having the about same problem. The whole cable bundle was hanging way lower than what is pictured in this thread. I don’t think it’s too much cable. I ended up putting a piece of 1.75 mm filament in the bundle to add rigidity. It has totally helped. I do think, however, I may get some 3 mm filament and replace it, This should make it sit up higher, while still giving it the flexibility it needs.
