About this model

---- Sanding required for snug fit. ---- Fine Sandpaper will do. (P400) The cylinder slides free if the all the pins are aligned correctly, so I would recommend to add some kind of restrainer to prevent the cylinder from sliding out. I would recommend placing the bed a bit closer (paper thickness + slight friction) to the nozzle so both sides of the lock look nice. The lock works best/smoothest when both the cylinder and the cylinder holder are exactly aligned. You can do this by pushing them flat on a flat surface. TODO: - Add a mover thingy and retainers to ensure that the cylinder stays in place. - Add some kind of arm that the key moves when its unlocked. Instructions: 1. Print The Key (Key.stl) 2. Print The Lock Cylinder (Cylinder.stl) 3. Print The Outside Housing (CylinderHolder.stl)…
