Hello,

For this year Valentine's Classics, I made this small Heart Shaped Box (not by Nirvana). 

I designed this box in Fusion360 and I am placing STEP file for anyone who would like to modify it for themself.

The bottom part includes little round bits to open the box easily. The sliding is very precise and to be honest it looks cool, try it yourself!

Print:

The dimensions are precise for fast print, the perimeter walls are 0,4mm thick(1perimeter layer) with thicker bottom. Print both parts with full layers on print bed.

I recommend to print in different colors and I am looking forward to see many fotos in comments!
