The Voronoi heart is a really simple 3D print any printer should be able to print. Size is standard size is 62 x 62 x 4 mm. The print setting don't really matter. I used red PLA filament with 0,28 mm layer height and the lightning infill, however this print should work with any settings. I recommend using a textured plate for a nice surface finish.
You can also scale the model however you want to suit your needs.
