Summary

Used openSCAD to cut the heart from the dragon model.

OpenSCAD didn't want to work with the full resolution version of the dragon so I trimmed it down a bit in meshlab. (dragon_lowres_ascii.stl) I used the heart thing http://www.thingiverse.com/thing:6190 to clip the heart from the original model. Then clipped the bottom of the heart so it could be used as the heart for the final print.

Instructions

I printed this in parts and it seems there isn't enough gap between them. They don't fit together very well. Probably due to slicing/printing errors. So you may find that scaling the heart down a tiny bit might help.

Also my print is scaled up 2.77 times which might make for more fitting problems. Getting the heart in there was tricky. I wound up having to heat the leg a bit, slip the heart in and bend the leg back. I used PLA, ABS may be more forgiving. The heartless-dragon.stl and dragons-heart.stl are the files for printing and they are the original poster's size.

Perhaps you dual-struders could do a nicer job. The models are located wrt each other and should be usable in that fashion.

The SCAD file, dragon_lowres_ascii.stl and heart.stl are included in case anyone wants to do a bit better with the SCAD-ing. NOTE: I had to go in and trim a few polys I couldn't clip in openSCAD without sacrificing too much tail detail. Making the heart bigger to clip these polys wound up eating too much into the tail.

Great model, Thanks to Andreas for great Thing. If you print this version of the dragon please use the original thing (http://www.thingiverse.com/thing:17204) to display your "I made one"

Had some problems getting the heart into the dragon's arms, without breaking off that foot. Any suggestions? I printed it in two pieces with a Makerbot Rep 2.

I printed in PLA and heated the foot a bit in hot water. Then slipped the heart in and smoothed the foot back down.
Not sure a reliable method if you used ABS. You could try holding a soldering iron under the leg, just don't touch it.
You will have to move quickly to get the heart in before the ABS cools.

this model will be the greatest valentines gift.

Just saw that you've already did this after I've uploaded my parts version. Well done! :)

And I just saw that I got a feature. :) Or I should say you did. :-D Thanks for the great model!

Nice, this little guy actually made a tripple feature :-D

Well played to you. I think you have a winner.

Worked pretty much perfectly with dualstrusion. I did make a few minor changes to re-position and re-size it by doing this:

scale(2) translate([-17.17, -20.8, 0]) {
import("heartless-dragon.stl", convexity=40);
//import("dragons-heart.stl", convexity=40);
}

Yes! I just clicked the I Like It button 10 times.

Since it turns into the Unlike button, don't you need to click it an odd number of times? ;)

Put a gem in it's claws so it's less "February".

And that's what I love about this place. I was thinking it would be cool if Andreas made a dragon with something non-Valentine but I didn't think to do it. :)

Yeah I'll work that up. Unless someone else beats me to it.

Haha, given it's expression the only other thing I can see it holding is a teddy-bear.

You kidding? Dragons are always like that about their hordes of gold and jewels.
