filletEdge 0.5mm causes naked edge?

Can someone FilletEdge this as shown along the one edge so as to avoid nakedEdge please ?

Need to send off urgent and beaten by this. I am mentally drained after battling boolean failures and other things, and cant focus on this minutae. simple edge and I get this just when I am all in.

here is file.

Hi Steve- run MergeAllFaces first and then FilletEdge.
Any better?


Hi Pascal, that works,

trouble is I have carried out so many unions since this that I have now to retrace my steps and use this fixed one.

unless I can explode all, fit the better part in then join all together again.

will try that first !
