It partly depends upon what you refer to as "failed". Many times the automated checks are SUGGESTIONS, not "failures".
The edges of triangular sections are often flagged as errors, when they actually are not an issue.
Just because an edge is flagged doesn't mean that it can't be printed.
There are a couple of different ways of describing what will work, depending upon how technical of a description you are interested in. Neither of these are "official rules" - just a way that we designers have come to understand it.
1) The angle of an edge needs to be greater than 52 degrees.
2) At 2*MinimumWall back from the edge, the item needs to be MinimumWall thick. (for FUD, at 0.6mm from the edge, it needs to be 0.3mm thick)
See the attached image.. your model has a sharp edge internally where two parts did not fuse together. I'd suggest fixing that.
Second,
@Youknowwho4eva is correct .. those two items that are 37mm*1mm are likely to be a problem. Not so much for the capabilities of the printer, but rather due to the fact that those parts are going to get broken/lost in post-processing. You should arrange something to trap/hold/protect them.
Take a look at this model..
