You Unlocked My Heart - Valentine Gift Box

This heart box is made of a base, cover and ring that locks the top and bottom together.  It says “My Valentine.  You unlocked my heart .”  

The design concept for this is provided by V Murano on his Desktop Makes U-Tube.  I modified his square box to a heart shape with greeting and left hand nut.

The nut's thread is 18 mm, left-handed.  It is so unusual that the author struggled to get the nut on the first time until he finally remembered to turn it counter-clockwise to put it on.

If you do not want to challenge the recipient with a LEFT HAND thread, I modified the design to provide RIGHT HAND threads, which will be easier to work.
