Overhang appears in the bottom of this
model, and it belongs to assembling
part.

Assembled parts can be printed
separately and reassembled later.
7.3 Assemble matching graphic tolerances
If the printed objects are graphics that need to be assembled, such as the matching of
screws and nuts, gears, due to the heat expansion cold shrink of the plastic during printing
process as well as the underlying swollen edge printing, the tolerances need to be
enlarged a little, general tolerance is set to 0.4 mm, depending on the actual graphics
settings.
7.4 Big size model print
If the printed volume is relatively large, you must use PLA filament, ABS filament
characteristics itself determine that it is not suitable for large-volume graphics, easy to
crack and deformation. Therefore, large-size graphics require the use of PLA.
If the large-volume graphic print process is still prone to warping, use the 502 glue to
stick the bottom of the image, but remember don't let 502 block the nozzle.
