Combination safe Vier

You must print 4 parts of the pieces called "outer dial" and "inner dial" to complete the coding part.
To select the combination code, you must match the notch in the part "inner dial" with the number in the part called "outer dial", then slide the dials in the "notched tower". The arrow on the bottom indicates the number. Then screw the nut on the tower until the rings are easy to turn and the two notchs match. To close the safe, insert the plug into the tower with the correct code till the end, and then turn the dials to safe it.
