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.

Big size model print
If the print volume is relatively big, PLA filament are needed, the feature of ABS
filament decide that it is not suitable for big volume graphic, it will easily split and out of
shape. So PLA is recommended for printing big volume graphic.
If the big volume graphic is still easy to get edge warping during printing, you can use
502 glue to stick the bottom, but do not put 502 to the nozzle.
