 Well, this could be a bug in Boxes.py but there are a few more likely causes to check for:
 
-* The material you use does not have the thickness you think. Measure it with at least a caliper. Even a few hunderdth of a milimeter will make the difference between a loose fit, a light or a heavy pressfit or no fit at all.
+* The material you use does not have the thickness you think. Measure it with at least a caliper. Even a few hundredth of a milimeter will make the difference between a loose fit, a light or a heavy pressfit or no fit at all.
 
 * You might have choosen the "burn" value too big. As it compensates for the material cut away by the laser smaller values make a looser fit, bigger values make a tighter fit. The right value may be different for different materials and different thicknesses.
