This is just a remix of the great designs of Quilling heart. by TanyaAkinora, and Heart Box by Microsoft. Using Tinkercad I just joined the Quilling Heart (without the inserts) with the Heart box. Since the Quilling heart stands proud of the box I Printed it with supports for the interior cover.

I used PLA with my normal print settings. I did change the infill to 100% because I filled the Quilling Heart with red epoxy when I was done.

I used Hatchbox PLA wood filament which sands and stains very nicely.

Fill with some candy hearts for a quick V-Day gift.
