Each of you probably loves all sorts of things with a secret.
In this article, the author of the YouTube channel “Engineer Bruns” will tell you how he made an extremely unusual keychain in the form of a cube with a cache for a memory card, or jewelry.
By the way, such a keychain does not necessarily require heavy milling. Such a homemade product can be cut out of a wooden block with a jigsaw “on the knee”, drilled a couple of holes with a screwdriver, and processed with sandpaper.
Materials
- Bronze and aluminum round timber
- A pair of neodymium magnets
- steel bar
- Second glue.

Manufacturing process.
So, the master begins with the manufacture of blanks. Slices two rounds of bronze and aluminum on a band saw.
Levels the ends of the received “washers”
Then begins the process of turning the workpieces into a box. First grinds one face.
Next, grind the rest, periodically turning the workpiece in the table 90 degrees.
As a result, we got these two parallelepipeds.
Now he turns the table 45 degrees, and makes two cuts in an aluminum billet.
Also mills a place for a cache in the central part.
It also makes a recess for the castle.
Sets a dovetail cutter and mills its grooves.
Here is such a first element with a cache turned out.
Now he returns to the bronze blank, in it there will be one cut and two side saws.
Milling the central cut and side cuts.
It also drills a blind hole for a magnet in a corner.
That's how the details fit together perfectly. It remains to grind them, and polish.
Now you need to grind the most important part. Locking cylinder. It is made of steel bar, and will have two small protrusions at the ends.
Two neodymium magnets are glued into the recesses of the parts.
Now you can hide in a cache, for example, a USB flash drive with important data.Then install the lock in the hole in the aluminum part, connect them together. To close, it is necessary to turn the structure with the aluminum side up and slightly tap it on the palm of your hand. Constipation "jumps" to the other side, and blocks the movement of elements. To open - everything is in reverse order.
By the way, even if you manage to unlock the lock, then guessing which way you need to move the elements will not work right away either. Here's a tricky secret. So that hidden values do not rattle inside, you can wrap them in cotton wool.
Thanks to the author for an extremely unusual idea for a micro-cache!
All good mood, good luck, and interesting ideas!
