Bath Fan Grille Torsion Spring Bracket
This bolt-on L-bracket replaces the broken spring tab on a ceiling exhaust fan grille. It fixes the grille that falls because its plastic spring tab snapped off. Put the 40 x 20 mm base against the back of the grille and fasten it with two M3 screws and nuts through 3.4 mm clearance holes, 28 mm apart. The 24 mm gusseted upright has two 2.4 mm holes, 10 mm apart, that take the hooked ends of the original wire torsion spring (about 1.5–2 mm wire). The part prints on its side, so the spring pull runs along the layers instead of across them.
