3d printed locks

3D printing models

General printing instructions

All prints are designed for a fixed layer height of 0.15mm (see layerHeight in util.scad). It is important that the first layer also 0.15mm high (the default is larger in many slicers).

Elephant's foot compensation should be used for all parts as well.

Instructions for generating stl files

All models are made with OpenSCAD. Run make in a subdirectory to build all the stl files for that model.

3D printed locks

Several 3d printed locks and related ideas. These locks are all designed with anti-pick features

Finished:

• disclock: A disc detainer padlock, with a reverse sidebar.
• euro-twist: A standard euro cylinder lock, but with a twist. Designed to use standard pins and springs.
• lever-lock: A lever lock with a curtain that blocks access to the levers. Can not be picked with standard wires.

Mostly finished:

• splitlock: A lock with a split key, which is held together by magnets. The key pins are inaccessible from the outside.
• rotate-wafer-lock: A lock with both rotating discs and sliding wafers. The key shape makes it virtually impossible to access the rear wafers.
• waverlock: A waferlock with a very large bitting range. The back wafers can not be accessed with a straight pick.
• combination-lock: A combination padlock that can not be tensioned by pulling the shackle.
• button-combination-lock: A combination padlock with sliding buttons
• magnetic-disc-lock: A lock with magnetic discs, based on a commercially available lock.

Work in progress:

• combination-lock2: A combination padlock that locks in the combination before tensioning the lock

Other:

• tools: Locksport tools, such as pinning tweezers.

Puzzles

Finished:

• puzzle1: A puzzle padlock, based on gravity

Work in progress:

• puzzle2: A puzzle padlock using a maze
• puzzle3: A puzzle padlock where bearing balls are moved around
• puzzle-frog: Make the frog into a princess.
• puzzle-maze: A twisting maze puzzle
