This clever design prints its 4 pieces as a single part. Download it here:

The video shows how it works - and it really does work that way.
It is a single STL file with multiple pieces; the Thingiverse site lets you customize the part for different printer characteristics, but I printed it as downloaded with no changes.
To print this I used the Craftware slicer, but this slicer requires some minor GCode modifications to run on an Atom2. What's required is to comment out 2 lines of GCode near the start of the GCode file. Here are the first few lines of the Heart GCode:
; GCode generated by CraftWare
G28 ;Home
G29 Z+0.5 ;auto level
;
; Comment out M83 & GF100E30 following M109
M109 S200 ;set and wait head temperature
;M83
;GF100E30 ; startup extrude
; ------------------------------------
; Raft Layer #0
To use Craftware you have to comment out the M83 command; if you do not do this the Atom2 behaves very badly and I had to reload the printer's firmware to recover from this. Adding the ; as the first character in the line makes the whole line a comment.
I also commented out the GF100E30 command because this pushes some filament through the extruder and it takes quite a while to do this. You could leave this in if you are more patient than I am, or if you aren't sure your filament will feed OK.
My Craftware settings add lines 2 - 5 above and tell you what needs to be commented out. I'll create another post that has my Craftware settings if you want to try them.
