Extended Strike Plate For Mortise Style Doors

thingiverse

Sometimes these door strike plates become worn out over time, or the mechanism within the door (the bolt of the knob or the lock) fails due to prolonged use, lack of lubrication, rust, and other issues. Once a door begins sticking, you can try the following solutions: A. Replace the mortise lock system; it's not expensive, costing around 20-30 dollars, and works perfectly well. B. Shim the original strike plate so that it extends further outwards. C. Shim the door hinges to make the door extend further out, thereby ensuring the bolt reaches the strike plate. D. Use the old mortise system and print this piece, which will increase the reach of the bolt; if the bolt only comes halfway out, now it will reach. Feel free to adjust the Z height as per your requirements. The central hole is large enough to accommodate most knob and lock bolts (both bolts in one hole). The screws are designed for flat head #8 screws with a 4 mm thread. My house is old, so I used #8 x1-1/2inch wood screws with a flat head; the specifications include a 3mm head depth, an 8mm head diameter, and a 4mm thread width for the holes, allowing me to get deep into that delicious, rotting wood.
