How To Make A Lego Bank Vault To Keep Your Money Safe

We have a fun LEGO® projection idea for you! Build a LEGO® safety with a working lock and key. In this mail, we'll show you more than than one way that kids can approach this projection. After learning some basic techniques, kids can pattern their own. Such a fun STEM building challenge!

LEGO® machines are so fun to build. It'south awesome to build something that really works! Kids volition besides bask this LEGO® catapult and this LEGO® candy machine.

This project can easily exist an technology Stem lesson. Learn virtually levers and mechanisms – more details below!

My oldest son designed the mechanism for the first locking box, and then I congenital the box so that information technology would look dainty. We make a proficient team. He's a great engineer and comes up with mechanisms that I could not create, but he doesn't do "beautiful" or making things look artistic. I can handle that office!

And really, kids can build this using any colors they want. We show our LEGO creations in solid colors because the photos are much less visually distracting and information technology's easier to see what's going on, but kids can do whatever they want!

See that nighttime gray drawer on the left side of the safe? It won't open unless y'all employ the key!

The safe (or you tin can call information technology a coin bank) has a slot for coins.

To open the drawer, slide the key into the box with the teeth facing upwards. Slide it in all the way.

Then turn the cardinal to the left. For security purposes, it's fun to make more than i key. Only 1 will fit the lock and open the drawer. Merely siblings and friends won't know which key is the correct one!

How to build a LEGO® Safe with a Key:

I would recommend starting with a 16 x sixteen plate. It's a good size for building a drawer that isn't huge, only can hold plenty of coins or other objects.

Decide what size you want the drawer to be. Cover an surface area that size with tiles then that the drawer will be able to slide hands. The tiles shown brand a 12 x 12 foursquare.

You lot'll need a wall of bricks in front end of the drawer and in back of the drawer. Exit one side completely open. On the other side, yous'll need to build a channel for the key.

(We'll talk about that pin sticking out in a minute.)

Hither's how the key works. I removed a few more than bricks and then that you can see everything conspicuously. The idea is that the fundamental slides into the channel. When you turn the key, the teeth fit through openings in the wall and push the drawer open.

To utilize the key, you'll slide it into the channel. Slide it all the way in until it hits the back of the prophylactic.

Build a 12 x 12 drawer. I used 2 6 x 12 plates and attached them with a 4 x viii plate. The drawer is four bricks high. And then in that location is a row of tiles around the height.

So plough the key to the left. The teeth on the cardinal should push the drawer out.

The drawer does not come out far on its own. This photo shows how far the drawer volition pop out. Then you can utilize your fingers to pull it out the rest of the style.

You can use a pin to keep the drawer from sliding out when y'all don't want it to. Slide a pin into a Technic brick and build information technology into your safe. And then add a Technic brick on the drawer.

Make sure that the height of the pivot lines upwards with the height of the hole on the drawer!

Once yous get the machinery working, identify the drawer in the safe. So build up the sides so that their height comes exactly to the height of the drawer.

If you want a coin slot, add a i ten iv tile to the peak of the frame. So add another row of bricks.

Finish upwardly the car by placing a sixteen x sixteen plate on peak.

And then build some decoy keys, ha ha. The one in the heart is the one that works.

Here'southward a second way to build a LEGO® prophylactic.

This is a absurd design because it demonstrates the apply of a lever. When you push the key forward into the safe, it pushes on the bottom end of a lever, which pushes the top end of the lever (and the drawer) forwards.

We establish this design on YouTube and congenital it according to the instructions. I'll include the video beneath so that you lot tin can build your ain! It's such a clever design.

Push the key into the slot on the bottom of the safe.
