Tool to align the band saw fence to the cut direction of the blade. Sometimes the blade isn't aligned to the fence. This small ruler type tool helps to check and align the fence to the cutting direction. The result is a better surface and you can cut smaller pieces.
I've printed this tool with PLA and designed it for 3mmx10mm magnets. The hole for the magnet have 3.2mm to press the magnet complete into the hole (magnet don't touch the blade). With my magnet I can use the ruler on both sides.
