I created this because the bowden tube moves and bends quite a lot when printing. While I'm not sure if it is of any great help, at least it looks nice :)
Installed using normal hot end screws, those are long enough.
This is for the first version of the Mega. The ultrabase version has zip tie in the bowden connector that fits if you cut a slot for it in the bottom. See comments.
Probably works as well with other layer heights.
