Create a Valentine's gift box for my two beloved ones and share its content in this video: https://www.youtube.com/watch?v=c0InwENdgh8. Here's how I printed it using supports with these specifications: 10% infill, 3 walls, and a layer height of .30. For the key, I chose 100% for strength; however, some parts might need slight sanding due to tightness.
