This is a replacement table insert for a Grizzly G0817 Bandsaw. Oftentimes something will catch and break these things. It's a pretty simple and quick part to print and replace.
My personal suggestion is to print with about 50% infill and in PETG for a bit of extra strength.
Print flat with tabs upward.
This part should fit flush and snug into place.
