[MOC] Indestructible box

[arik]

Hi,

have been away for a long time, but now I'd like to present something small I came up with: an indestructible box, meaning a box that cannot be disassembled without damaging the parts. The only way to take it apart or to build it, is to unlock the securing pins inside the box. So if you use one of the sides of the box as door (with a lock!), then you got an "actual" safe.

I haven't been able to find this kind of creation before, so hopefully my idea is useful for others thinking about it.

In this model the "door" is the front panel secured with grey 3M pegs that you can pull out from outside. The red beams are the frame, yellow parts keep the frame secured, and grey parts provide walls, that also prevent the frame being disassembled.

Here is the frame without the grey panels, where you can see also the securing pins (4M with end stop, shown in the locked position):

When the 4M securing pins are pulled out, the top part of the box can be lifted and disassembly is possible.

Here is the LXF file as well if you want to take a closer look: LXF FILE

Do you have ideas for a locking door? It could be combination lock of some sort, mechanical, pneumatic, etc.

Also is there a way to disassemble this without opening the door that I didn't think of?

There's also another topic for assemblies that can be put together but can't be disassembled by normal means. Though I'm not sure how you would go assembling this box in a way that prevents disassembly?

Also, not long ago someone linked in another topic a video of a safe which the creator claims cannot be opened without either the right combination or damaging the parts.

Thanks for the video link, haven't seen that before! Unfortunately can't see how he prevented disassembly, it was surprisingly difficult to design (for me :-)). Anyway, the locking mechanism is really cool!

I remember the topic for "one-way" assemblies, that probably got me thinking about this originally.

If you want to make this box impossible to disassemble, then create a door that locks automatically (a springed latch for example). Or push an axle from the side to lock the door and prevent it being pushed all the way through.
