Small stuff kept falling into my table saw - replaced the blade cover with a snug one. First print fit perfectly!

And with a zero clearance insert you should see less tearout on the bottom of whatever you're cutting!
If you save the outside dimensions and fill in the hole where the blade is, you can make the blade hole perfect just by lowering the blade and raising it through the insert.

Congratulations on reinventing the zero clearance insert. :-)
Seriously, though, I've been using this approach for years and it has so much win.

I'm not a wood worker, but wouldn't it just be easier to drop in a wooden insert and plunge the blade up through it, creating something that has no gap?
I would have preferred a wood insert as you described, but had no means (or sufficient creativity) to make one. I did plunge the blade through the solid PLA.
That's a very dangerous procedure. One of the biggest rules in woodworking is keeping your hands away from the table saw as much as possible.
Edit: Yeah, I was wrong. My bad, guys. I personally am against plunge cuts due to safety, but I forget that other people do them do them safely all the time.
We do plunge cuts all the time. In fact the other poster is correct, it's common practice when making a zero clearance table saw insert by cutting out the original shape on a band saw (or the like) then to insert and raise the blade to create the slot.
Yep. And it's safe as long as you put a hold-down on the insert and avoid standing directly behind the path of the blade when you're raising it.
IRL, safety is mostly working in a diligent fashion and understanding the nature and limitations of both your tools and yourself. That goes for table saws, 3d printers and a whole lot of other things.

I'm honestly asking: What part of this is dangerous? I guess where he freehands some sanding against the big disc sander, but that's all I noticed.
