This Secret puzzle box works with the wheel technique. Weights for the wheels are M4 nuts or anything from steel that fits snug in the hole of the wheel. Different orientation of the wheels make different combinations to open it. Decoration of this box is with a Lotus flower but there are many download decorations available on the Internet. The lock and top lid are glued together with super-glue. The lock lid also contain the lock pin so you can not open the box to far so the mechanisme NOT becomes visible, after testing the box you can glue the pin and axel so its keeping its secrets for others.
I hope you enjoy this one.
