I have been printing rc airplanes. The current one has locating holes for the wings and fuselages.
I have found that I needed to open these up slightly to make them accept the specified pegs.
I just noticed that Cura has an option called 'Hole Horizontal Expansion"' stating that a positive value would increase the size of the hole, while a negative value would decrease the size of the hole.
I applied a figure of 0.05mm to this, thinking it would enlarge all holes by 0.05mm, however, it has had the opposite effect, and has actually made all the holes smaller. It is a bit hard to tell how much smaller, but it would even appear to be more than the specified 0.05mm.
I will have to print the wing again, and this time I will try using -0.05, and see what happens.
Could you please have a look at this, as these parts have a 9 hour print time ...
thanks Dave.
