Love Seen Through

Remix of another model - I like this for it's quick print (less than 1 hour). I removed the top and bottom layers, making it see-through, and switched to gyroid infill pattern which I think looks rose-y, making it just a little extra Valentine-ish. 

In “Preview,” it will look solid, but once you go to preview mode, the exterior layers will disappear showing you what the final product will look like. You can mix up the infill to get different effects, my second favorite is Octogram Spiral and Archimedean Chords. 
Concentric and Lightning will not work without the top and bottom layers!
