The Heartbreaker: World's Most Annoying Gift Box, 51 Screws | Valentine Heart Puzzle Box

51 screws stand between them and their gift.

It looks like the sweetest present in the room: a glossy heart, a pink ribbon, a big bow on top. They lift it, admire it, turn it over looking for the way in, and find a band of screws running all the way around. Three rows of 17. They pick up the screwdriver. They count. They lose count. Fifty-one screws later the lid finally lifts, and there's the gift you hid inside.

The Heartbreaker is the World's Most Annoying Gift Box in its most romantic form: a two-piece heart whose lid's inner wall drops inside the base, held shut by 51 countersunk screws, finished with ribbons and a bow. Romantic gifts are easy to forget. Nobody forgets the one that needed a screwdriver.

Then they can screw it all back together and save it for your anniversary.

💘 MAKE IT THE GIFT EVERYONE TALKS ABOUT

• Seal a gift card or folded cash inside for Valentine's Day

• Hide earrings, a necklace or a ring box for an anniversary they'll never forget

• Fill it with candy and a love note, then hand over the screwdriver

• Anything up to about 117 x 97 mm and 70 mm deep fits inside the heart

🖨 WHY YOU'LL LOVE PRINTING IT

• Any printer: every plate is a single color, so you don't need a multi-color setup or a second nozzle

• No supports anywhere and no glue: the screws and press-fit ribbons hold it all together

• Ready to print: the Bambu Studio 3MF has all 5 plates laid out, colored and tuned. Open it, pick two colors, print

• Screws that print cleanly at 0.12 mm and thread smoothly into the lid

• Pick your two colors: red and pink is shown, and black with red or blue, or pink with white, look just as good

• Solid and reusable: unscrew it, refill it, regift it

• A 12-page illustrated guide from the first plate to the bow, with a screw map of all 51

PRINT SETTINGS

• Printer: any FDM printer with a 0.4 mm nozzle. One color per plate, so no multi-color setup or second nozzle needed

• Plates: 4, plus an optional 5th for a screwdriver. Color A: the base, the lid and the 51 screws. Color B: the bow and the 8 ribbon pieces

• Material: PLA, about 372 g for the box and all 51 screws

• Layers: 0.20 mm, 2 walls, 15% grid infill. The screws print at 0.12 mm for clean threads

• Supports: none

• Scale: 100%, so the screws line up with the lid's threaded holes

• Bed: the 3MF is laid out for 256 x 256 mm beds; the biggest part is the 157 mm lid

HOW IT GOES TOGETHER

• The four bottom ribbons press into the base, the four top ribbons onto the lid

• The gift goes into the lid, turned upside down

• The base slides down over it until the halves meet

• All 51 screws go in sideways through the base, into the lid

• The bow presses on last, where the ribbons cross

The guide's screw map shows where all 51 go.

FINISHED SIZE

167 x 145 mm and 124 mm tall (6.6 x 5.7 x 4.9 in) with the bow. The heart-shaped space inside is about 117 x 97 mm and 70 mm deep (4.6 x 3.8 in, 2.75 in deep).
