Hi guys!
I was looking for ideas and I found this model: https://www.printables.com/model/26611-heart-puzzle-brain-teaser.
Inspired by this model I made the Heart Puzzle!
I´ve desihn the puzzle “solution” on the bases base, to make it easy to assenble ;)
I've also included the Fusion360 file, so the design can be edited and personalized with dates, names, etc
I recommend to print the heart in red and the base in black, as seen in the image.
Hope this makes your other half very happy. <3
