I made this quick little gauge to see what size my slicer will recognize. For me, Bambu Studio recognizes down to around 0.45mm. You really don't even need to print, just slice to get an idea of how small a piece you can model that will show up. I used this to to model 0.5mm standoffs for a part and I was successful. Layer Height did not make a difference for me, which now thinking about, makes sense.

First Picture = PreSlice

Second & Third Picture = Sliced (notice starting at 0.40mm cylinder is missing)

God Bless!
