Makita Bandsaw LBF1200F insert plate
I've remixed the model, changing the height to better fit (no more protrusion), and also added a slight bevel on the underside, as the cast iron had such a profile on my bandsaw.
I print it with 2mm-thick walls, and a 25% infill, but basically it is like a 100% infill as the total height is below 3mm.
