bar clamps - could be a bit taller above the nut

Hi :-)

In my configuration and slicing with Skenforge I've discovered some bug. The bridge above the nut starts too low, so there's a gap just above the nut. This is a visualisation of this layer made under YARRH. Obviously it can't be printed properly


The solution is to make one more solid layer just above the nut, so the bridge will have no gaps.

Slicing with 0.3mm layer height, the same height set in M90 config. However I had no problems with 0.4mm when printing my first M90 ever.

Yes, the top of the nut trap needs to be below the roof of the hollowed out bit.

I haven't tried changing the config layer height so there are probably a few bugs. I have sliced some things at 0.3 with it left at 0.4 in the config and that works.
