I had seen an animation of this safe online and thought that I might try to replicate it to bring it to life so to speak.

I've made it as small as I can using the standard 0.4 nozzle.

This mini safe is fully 3D Printed and all components are on the same build plate with no supports.

The main body and door are print in place with the back component printed separately, this is a push fit but can be glued in for a more secure fit.

All the components are a push fit, some components need to be tapped together using a suitable plastic mallet.

Assembly:

To start off with, I located and pushed in the door stop components, these are different so align the pins with the holes and then push in to fit.

Next is the sliding lock mechanism, align this with the locking pin facing the keep in the main body, this is secured by the 2 stand offs, align these with the recesses and push in to fit, the 4 segmented dials can now be aligned and and pushed into the holes on the front of the door.

Taking one of the locking pins, align with the hole and push through, align the slider so its in the open position and push the knob on aligning the marker on the knob to a segment on the dial, the same applies to the next 3 pins, choose a different segment each time, these will be the positions when you want to open the safe, there are 12 posions on each dial, think of these as hour segments on a clock.

When you have all these in place, write down the positions of the dials or take a photo, close the lock using the gear knob and then to lock rotate the 4  knobs randomly, to open use the initial positions, when happy that it all works, the back component can be fitted, this is a push fit but can be glued for added security.

All components on one build plate and no supports.

I'm thinking this will probably scale bigger but I haven't tried it.

Check out the video to see the safe working.

Great Little project, really enjoyed designing it.

Thanks for Looking.
