Solved this perfectly, and I believe also gives improved thermal insulation due to the air gap, but this may be insignificant compared to the route throgh the scres, but certainly does no harm.Quote

- You can put a couple of extra washers between the mdf spacer and aluminium cooling block, if you are still having problems.

Also, when attempting to print something the fan duct pushes the bulldog clips off the bed as it moves to one end

On top of all of the useful stuff Ian wrote: On mine I also found that looking along Y and making sure that the whole thing was level also helped - I loosened off the screws holding the fan duct to the heatsink and mount, then twisted the assembly until it was level to the bed's X axis (ie looking from the Y motor along the Y axis, the bottom of the orange case is horizontal relative to teh bed and the x axis rib) then I tightened up the screws and that massively diminished the number of drag-offs I had from the fan ducts (which were almost always from the corner opposite the z-probe)Quote

- Looking along the x axis, check the hot end is square, not sagging down. Adjust the x-carriage idler bearing (on the back of the x-axis-plate), to lift the hot end up.

I think everyone has removed that clip for this reason!
I run my bed with the three remaining clips without problems, but I will follow the modified clip post (which I can't find!) where the top side is cut down to make it flat. You need a adapter to get it on the bed, but the design of this was also covered.
There has also been some posts using glass picture frame clips which also look good.

My sensor is fine but the fan duct keeps hitting the bed clip no matter what I do. (pic attached)

Is the only solution for this is to get new clips?

Also I tried adjusting the x carriage idler bearing but it doesn't really make much difference. At the tightest angle, the carriage still sags a little bit. Is it supposed to do that?
