Could use fine sandpaper or a dremel, or carefully trim it with an xacto knife.
From what I remember when I had access to a 3d printer, it would overfill the first layer like that by default for better adhesion to the bed, but it was adjustable in software.

I have not personally experienced this, but I would consider scraping it with a razor knife first.
For sandpaper, 400 grit should be plenty fine enough. Those polishing papers take away so little material you could spend all afternoon on it.

Hi, highly recommend using knife in addition also flat cutters/nippers to remove the material.
Sanding should only be done later and in a progressive grit. The little edges are long strands from the printing process and the plastic might sort of delaminate at the edges if you try to sand it first. As its of course connected to the plastic beside it.

"Progressive grit" ⇒ use a coarser grit, clean, then use a finer grit, clean, ... and repeat with even finer grits until you are satisfied. The exact grits don't matter, only that each next grit should be just under twice the previous grit.
BTW, around 1000 is very fine: the next higher would be a polishing compound and a rag.
However, In this case, I would maybe sand the bottom in 320 grit or so to make it perfectly level, and then sand the edges lengthwise where there is flashing. Do wrap (or glue) the sandpaper around something flat to use as a "sanding block" to get flatness.

we miss an important bit. what material is that?
if PLA for example it's not easy to sand and absolutely do not use rotary tools (dremel)

Recommendations in the order of importance:
- set the printer z-height and the first layer thickness better to minimize the problem while still having good bed adhesion
- chamfer the bottom of the model before printing it
- use an utility knife to cut/scrap the rim off (this is typically not needed if you do the two previous points well)
