Heart Shaped Lock Box – Unique Gear Lock System with Key

Featuring a gear lock mechanism, this design makes it perfect for storing small treasures, love notes, or meaningful gifts. Ideal for Valentine’s Day, anniversaries, or any special occasion.

ATTENTION:

This design requires attention to be assembled. read below the step-by-step tutorial for the assembly process before you start printing it.

Step 1

Start printing Plate 1 — this is the first plate you'll need.
DO NOT PRINT THE SECOND PLATE FIRST.

Step 2

Once Plate 1 is printed, notice both top gears have an arrow on the top. Keep this in mind for the following steps.
Remove the gears from the plate and remove the support from the bottom gear.

Step 3

Start printing Plate 2.
Your print will include the key; if you’ve already printed the key, you can skip it.

Step 4

The printer will pause around layer 36 — this is normal.
DO NOT CONTINUE THE PRINT. Proceed to the next step.

Step 5

Take the gears printed on Plate 1 and place them as shown.
Ensure the arrows point up, and the bottom gear’s heart embossing faces up.
Make sure everything aligns exactly as shown — it will not be possible to adjust once the print continues.

Step 6

Once everything is in place, resume the print and let it finish.

Step 7

When the print finishes, the box lid should look like this.
The gears will now be locked in place and will not fall or move.

Step 8

Remove the supports from the indicated spots.

Step 9

Now it's time to lock the lid to the box.
This will act as the hinge. You’ll need some force to lock it in place.
Be careful not to break the lid during this step.

Step 10

Your box is now ready for use.
Simply use the key to open and close the box.
