I'm guessing that you used Ideamaker slicer not that it should matter.

I loaded your 3mf file into Prusaslicer and it shows that it has 4044 open edges, floating bridge anchors, loose extrusions and long bridging extrusions.

In that orientation you would need supports, is there any reason that you cannot orientate it 90 degrees onto the flat side as in screen shots

Are you leaving the top off and either removing the door or at least leaving it open for PLA?

What software did you design the part in?

I am still using the original PEI plate.
