fitment

[left seal]

Hi, I need some advice on fitment of parts. When I'm printing a box which interlocks I end up with teeth that won't fit together. They seem the same size. Also with multipart prints with pins. My pins usually don't feed unless I scale them down. Now I'm experimenting with the horizontal expansion. Does that need to be on both parts or just one or only on the pins?

Hope it all makes sense

Thanks

The fact that printed parts dont fit prefectly is normal, it's plastic stacked on top of each other, but look for the setting "wall ordering" or something like that and select "outer before inner"
