Some boxes, one, or all, to give to your loved one on Valentines day.
There are three versions.
One with a regular lid, one with a hinged lid and one with a sliding lid.
The one with the sliding lid is the fun one. When opened the heart will fly out making your loved one freak out (hopefully).
It has the text ´don´t break my heart´ on it.
You wil need a spring though. The one I used is 35 x 9 mm.
I printed it with basic pla+ from Esun and silk filament from Iemai (Amazon)
Only the hearts need some supports. I used slim tree support on diameter 1.
Best is to use gyroid infill because other infills like to throw them over.
Note: hold the hinges on the hinged one in hot water for a short while to soften them. Then put the two part together and put it in hot water again. Then squeeze them. They will will make a solid connection.
