Box lid doesn't fit
Hi guys! I'm struggling with a box that I realized by myself. My box has a top and a bottom parts that fit together with screws. As you can see from Fusion360 the measures are ok and the two part fits perfectly. But after printed them I noticed that the lid doesn't fit with the box...it fits only if I turn it upside down...I tried to change print orientation, to export from Fusion360 with different orientations but nothing... it doesn't work...could you help me?

Obviously even if I posted a picture that the box has a different orientation in the slicer plate, I also tried, as I said in the previous post, to export from Fusion with that orientation too...but nothing..
if the box is a simple rectangle, and it's misaligned like that due to different print orientation, your printer might be skewed, measure length of diagonals in your box, if they don't match your x and y axis aren't perpendicular to each other.
If that's the case, it's best to try fixing it physically by adjusting the build. small skew can be also fixed with software: https://www.klipper3d.org/Skew_Correction.html

Ok @pravvv I'm trying to fix with screw correction..I'll let you know, thanks!
I did screw corrections and created a profile with this result:
## [skew_correction vminion]
## xy_skew = -0.011364003572021884
## xz_skew = 0.0
## yz_skew = 0.0
but box lid still does not fit....
did you use calipers to measure what got printed actually matches your design?

by design measures should be 126mm (w) x 90.897 (h)
with calipers: 125.35mm (w) x 89.78mm (h)

what is your shrinkage rate?
optimistic-gold•16mo ago
where I can read it?
depends on the slicer, in super slicer:

I'm on Orca. Anyway I find it, 100%
What I do is print the 100mm stl this guy mentions and use that to calibrate the shrinkage (after I have done flow calibration)

Ok I'll try to calibrate with this method. But can this resolve the not perfect squared box? The box can be more accurate in decimals, but why the box lid fit the box only when upside down?
As you can see from my 5th picture the gap is almost 3mm
that's from before skew calibration correct?
optimistic-gold•16mo ago
before and after
are you setting the skew in your slicer?
