Fits well, but may need a little sanding to get that really nice snap in fit.
I've had some plop right in, and others need a little love.. :)

I use some 1cm M3 grub screws in the screw tabs to level it, and another at the end with the hole provided. I designed these with a 1mm hole on nearly everything, but they tend to become smaller with the print. The reason for them being there, it the software will re-enforce those areas, allowing you to drill in, and get the grub screws to thread.

You may want to add 2 more down one side to get it completely snug. Once it's leveled and tight, raise the table saw blade up and allow it to cut through, creating the zero clearance insert point of this thing's existence.

I then use one of my sharkfin kerf splitters (also on my account).
Cut out a notch in the end of the insert, by using an old one in place and very carefully lining up your fence to the slot already cut out by the blade.
Take your time with this bit. You want it to align perfectly.
