I thought the stock top plate tube holder was lacking so I designed what I consider an improvement.

It is the same thickness, that part was fine. I added some sleeves to help secure and support the two feeder tubes. I also added a split 2" long sleeve for all the wiring to feel into with two indentations for tie wraps. Another thing you can do is remove the horrid spiral wrap from the cable and replace it with 1" Grip Wrap Sleeving, http://www.cabletiesandmore.com/grip-wrap.php. It is the woven sleeving that the Makerbot Replicator has but is velcro like and has adjustable diameter. You can wrap your harness with it, overlapping the split sleeve and tie wrap it.

A great addition to the Flashforge Creator 2, imho.
