Deadbolt Combination Lock

thingiverse

This is a combination lock and deadbolt combined. The three cylinders rotate smoothly on simple gear bearings, with one of 17,576 possible unlock combinations. Once unlocked, the lock slides out of the bolt-keep. *Crack-resistant* - Each cylinder has 25 blind partial (false) lock pin channels, and one blind full (true) lock pin channel. All cylinders must align to the correct combination to fully pass the lock pin. Mount the lock on a door that opens in or out. Two versions of a bolt-keep are provided: one model that mounts parallel to the door, and another model that mounts perpendicular to the door plane. ###Usage • The lock has three sliding positions: Locked, Open (middle position), and Remove. Rotate the cylinders randomly while in any of these positions to hide the unlock combination. • Set the cylinders to the unlock combination to allow the lock to slide from the Locked to the Open position or Open to Locked position. Rotate the cylinders randomly to prevent the lock from sliding into the Locked or Open position. • Set the cylinders to the unlock combination, then rotate all cylinders 180 degrees, to allow the lock to slide from the Open to the Remove position. Slide the lock fully away from the bolt-keep until it can be lifted from the door mounting plate. ###Build • The lock prints on a 120mm build plate. • Assembled dimensions of the lock (not including the bolt-keep) are 4.9cm thick, 15.4cm long, and 9cm wide. • The door plate and bolt-keep are intended to be installed on the same plane. Separate adjustable mounting spacer models are provided for the door plate and bolt-keep for installations where the surfaces of the door and door jamb are not on the same plane. ###Parts Lists - M3x25 socket cap bolts, in stainless steel (qty 4) https://www.boltdepot.com/Product-Details.aspx?product=6384 - M3x16 socket cap bolt, in stainless steel (qty 1) https://www.boltdepot.com/Product-Details.aspx?product=6382 - M3 nuts (qty 5) https://www.boltdepot.com/Product-Details.aspx?product=4773 - Loctite super glue ultra gel control, for PLA. http://a.co/gHkket5 Follow the glue label instructions exactly!
