3 Pin Lock With Key

thingiverse

Sanding required for secure fit. Fine Sandpaper will do, grade P400. The cylinder slides freely if all pins are properly aligned, so I highly recommend adding some kind of restrainer to prevent the cylinder from sliding out. I suggest placing the bed a bit closer (paper thickness plus slight friction) to the nozzle so both sides of the lock look appealing. The lock works best and smoothest when both the cylinder and the cylinder holder are precisely aligned. You can achieve this by pushing them flat on a flat surface. To-Do List: * Add a mover thingy and retainers to ensure that the cylinder stays in place. * Add an arm that the key moves when unlocked. Instructions: 1. Print The Key (Key.stl). 2. Print The Lock Cylinder (Cylinder.stl). 3. Print The Outside Housing (CylinderHolder.stl). 4. Print Three of the Locking Pins (3XLockPin.stl). 5. Print Each one of the pins (PinA.stl, PinB.stl, PinC.stl). 6. Sandpaper the outside of the Lock Cylinder and the inside of the cylinder Housing. 7. When both pieces fit snug together, proceed to assembly. Assembly: 1. Align all pins to the key (biggest pin to smallest groove and vice versa). 2. Place all pins in the correct order into the cylinder. 3. Ensure that they all lie flat when the key is inserted (view image). 4. Remove the key slowly and insert the cylinder with the pins into the cylinder holder. 5. Insert the last 3 big locking pins into the cylinder holder. 6. Assure everything is lined up and flush with each other. 7. The lock should now work correctly. Known Issues: Trouble inserting or removing the key: Ensure that both cylinders are flat together. Pins getting stuck: Sand the pin slots/holes. This is a functional Work In Progress project. Please share and like if you enjoyed this project.
