Added in a side ring which sits over top of the allen head bolt, preventing the clips from slipping out. I was finding the bowden clips would move around alot and sometimes come off, then the bowden tube itself can pop out and the print fails. Simple fix and works well.
I also increased the thickness of the section which holds up the bowden tube clamps, as they were a little loose.
Ignore the fact I have my own printed fan shrouds, the mounting holes etc are all the same as the stock metal ones.
Editing STL's is not ideal, you can see a faint '4' on the ThingView, however it is not present in the actual model when you go to print. Ill look at fixing this.
