After a man and a woman fall in love, they often hold several events, one of which is to lock their love locks in a nice place. There will be many more events to lock these padlocks in the upcoming Christmas.
However, these have recently become a problem in many countries around the world, and are currently being demolished or have already been demolished.
Whether love bears fruit or breaks up, it is extremely rare to find a lock, so I came to think that filling a lock as a token of love is a symbolic thing and does not actually need to be strong. So this time I designed a lock that can be printed with a 3D printer.

Although the material of the 3D printed padlock is plastic, the structure of locking and opening is reproduced almost perfectly. However, some modifications were made to make it suitable for 3D printing, but rather, a new structure was created!

The process of making is as follows.
It moves very well if you apply grease, lubricant, or machine oil before connecting the parts.
1. Insert the rotating cylinder-shaped plug by pushing it in the center.
2. Insert the key into the hole of the plug and push it to check operation.
3. Finish by covering the half lock body. When covering the half body, please check the projections and holes carefully.
4. Turn the key again to check operation.

The principle of operation is that when the key is pushed in, the pin is pushed and moved, and the plug can be turned at last. As the plug rotates in this way, the latch is moved so that the shackle can be locked or released to allow movement.

Please check the detailed process through the video.

This lock should never be used if you want perfect security. But if you want to do something iconic or just fun locking, it's a great product.
We hope you have a good love event this Christmas with this love lock!
