Hidden Heart Valentine

This is a hidden Valentine heart. You just need to twist it to reveal the Valentine heart.

You have several options:

• Blank - Twist Lock: A heart with no letters on it, featuring a snappy lock in two positions.
• Love You - Twist Lock: A heart with the inscription "Love You" and a snappy lock in two positions.
• Blank - No Twist Lock: A heart with no letters on it, allowing free rotation without a lock in two positions.
• Names - Twist Lock: A customizable plate where you can insert custom names into the Valentine heart, with a snappy lock in two positions.
• Names - Twist Lock - AMS: For ams maniacs who want a different color for the custom name.

Assembly:

The assembly might be a little tricky, but this is the best way to insert the pin:

1) Take one half of the heart with the parallel ribs in the hole.

2) Align the flat surfaces of the pin with the ribs as shown.

3) Insert one side of the pin into the hole.

4) Push with your thumb the second side of the pin.

5) Push the pin until you hear the “click”.

6) Repeat the previous steps for the second half of the heart, except this time you don’t need to align the pin.

Size adjustments:

Although this model was tested on three different printers—P1S, A1, and A1 Mini—some people might still encounter tolerance issues. To achieve the best results, you need to adjust the size of the middle pin:

1) Choose the pin and press “Scale” button.

2) Turn off unifrom scale.

3) If you feel that the rotation of the two halves is too tight or too loose, adjust the X and Z scale by 0.5% up or down and reprint the middle pin.

4) If you see a gap between the two halves, adjust the Y scale by 0.5% down and reprint the middle pin.

5) Some PLA plastics might produce a squeaky sound during rotation. I tried to solve this problem with grease, but it didn't help. I had the best results with Bambu PLA and ESUN filament.

Custom names:

To add your custom names, follow these steps:

1) Go to objects → 4 plate.

2) Right click on text_shape → change type → part.

3) Right click on text_shape → edit text.

4) Input your text and properly alight it.

5) Right click on text_shape → change type → negative part.

I hope this design might help you express your feelings or bring warm and positive emotions to your partner.  ❤️
