About this model

This is an update to my Preassembled Secret Heart Box, which is smaller and much sturdier. I redesigned the latching mechanism so that it holds much more securely and doesn't wear out. I also designed this so you could easily put two initials on the box using Customizer. I find this works quite well as an earring box or pill box, or just as a handy stocking stuffer to fill with small treats. Enjoy! Note: this is a complex file, so Customizer's preview will time out, but if you click Create Thing, it will properly generate the object.
