**💖 Better Together – Magnetic Keychain Pack 💖**

**Better Together** is our Valentine’s 2026 project, featuring 3 adorable mix & match designs: Panda 🐼, Bear 🐻, and Cat 🐱. 

**~🧲 Magnets (optional but recommended)**
- Magnets are optional… but highly recommended for the full _wow_ effect 💖
- Inside the 3MF files you’ll find pre-made magnet slots (we used round D8×2 mm magnets).
- Pause for magnet insertion: layer 27 when printing at 0.16 mm layer height (**already set in the 3MFs**) or 4.36 mm absolute height
- **Using a different magnet size**? No problem! Resize the slots directly in your slicer (we recommend +0.5 mm tolerance compared to the magnet size). Check the [How To Change Magnet Size](https://www.youtube.com/watch?v=EHsJunQBDBw)  Youtube Guide.

**~🔑 Keychain (optional)**
- Available with or without the keychain hole
- We used **2.4 mm ringball keychains**, easy to find and very common
- Also compatible with standard classic keyrings (≈8 mm diameter)

**~🎨 Colors & multi-color printing**
- All models are ready for up to 4-color printers
- Bear version tip 🐻❤️👁️: swap the heart filament (red) with the eye filament (white) halfway through the print and you will get a **5-color design with a 4-color printer**!

**General recommendations ⚠️**
- Before diving into the multi-color print, we highly recommend starting with a single-color **test print** to ensure everything works as expected.
- For multi-color prints, we suggest **filling the bed** to minimize PLA waste from color changes.

**Files available 📂**
- Optimized **3MF** files for BambuLab, Creality, Anycubic and Elegoo for an effortless print experience!
- **STL** files for all printers

_We believe in true love, especially when it's 3d printed_❤️✨

Unlike standard articulated dragons based on simple chain links, this model features a spherical articulation that allows smoother, more dynamic, and more natural movements.

The result is a flexible dragon that can twist, wrap, and pose in ways that traditional designs simply cannot achieve.

Articulated Heart Dragon – Flexible Spherical Joint Dragon

Heart DragonSnakeART.stl

The Lover’s Valentines Game, a tabletop game made for 2 to 8 players. 

Just in time for Valentine’s Day - my most novel creation and possibly my greatest contribution to mankind… a way to get into all kinds of trouble and have a lot of fun.

To start: Each player has a Box Deck and a Heart Box. The player writes secret notes with instructions and puts inside of the heart box. What kind of notes? That’s up to you!
“Kiss me”
“Stand on one foot and bark like a dog”
“Sing a song”
“Imitate Christopher Walken” – ‘Hey, you’re talking to my guy all wrong. It’s the wrong tone’
“Tell us your greatest fear”

The heart boxes are then mixed up so that no one knows who has what. Each player has a base which the heart box sits in. Spin the arrow and when it stops, the player it is pointing at must open the box and follow the instructions in the heart box. 
Who goes first? It’s up to you to determine that. You can choose by age, last person to arrive etc. make it your own. 

Each player must make an equal number of secret notes before the game starts, and each time a box is opened it is replaced with another secret note. Keep the notes in a hat, bag etc. where no one can see what is on the note.  Make as many notes as you like for longer or shorter games. A DXF template file is included if you want to print heart-shaped notes to cut out, or you can use any piece of paper small enough to fit in the box. Play until all of the notes are gone. 

You can pass if you perform a task agreed upon by the other players. Example – If you don’t want to do what is on the note, then the group agrees you must quack like a duck etc.

For a 2-player game, this is a cheeky way to propose.

Variations:

Strip Poker (ish) – roll the dice, spin the arrow. The player that the arrow stops at must remove a number of articles of clothing based on the number you rolled. If you roll a 3, the player must remove 3 articles of clothing. It can get sticky fast. The game is over when someone is au naturale. 

For a fun variation guaranteed to have everyone dying with laughter - A player panel with a + - is included, give one to each player with the + - facing the player. At the beginning of the game each player must remove one article of clothing to start. Spin the arrow and the game begins with the person it stops at. If the arrow stops closer to the + sign, the player must put on the number of articles of clothing indicated on the dice. Example, someone rolls a 2 and the arrow stops at you on the + side, you must put on 2 articles of clothing, so you could end up wearing someone else’s hat, shirt, bra, socks… If there aren’t enough spare pieces of clothing – say you roll a 3 and there are only 2 items available, you put on what is available. You get a pass if no clothing is available.

If the arrow stops closer to the – side, you must remove articles of clothing based on the number on the dice. The game is over when someone is totally bare or someone throws in the towel. This is a great winter time game when it’s cold and miserable outside and everyone is wearing a lot of clothing to keep warm. Not for long, though 😊

Drinking Game 
The + - panel has a little socket, which by some divine magical intervention is the perfect diameter for a standard shot glass. Roll the dice, spin the arrow, the player the arrow stops at must take the number of shots indicated on the dice. Now you see why the dice only goes up to three…

For a more challenging variation, if the arrow lands closer to the + sign you must drink the shots, if it lands closer to the – sign, you have the option to make someone else drink your shots. Yeah, it’s gonna get dirty near the end.

And the best variation is for last.

Strip drinking game. 
Each player has a + - panel. If the arrow stops at or closer to the +, the player must drink shots based on the number on the dice. If the arrow stops closer to the -, the player must remove articles of clothing based on the number on the dice. 

You can also play classic group games like Truth or Dare or Spin the Bottle.

Simple, fun, endlessly customizable and entertaining. You can make an almost endless variety of games. 

Build and assembly:
You can use ordinary PLA with this model and make it as colorful as you like. I print with 4 walls and 50% triangular infill with properly dried filament – tolerances are critical for smooth spinning.

Print the base and 8 Player Indicator Panels. You can glue these into place if you like. Print as many Box Decks, Heart Boxes, or + - shot glass panels as you want. Print the spinner arrow. Note the arrows in the picture are printed with exposed infill and no bottom layers for appearance.  

The design is modeled for this type of bearing:
https://www.amazon.com/XiKe-6000-2RS-10x26x8mm-Pre-Lubricated-Performance/dp/B07S8K6N6Z/ref=sr_1_4?crid=3TWCUX0GP9QN6&dib=eyJ2IjoiMSJ9.tUoU75-kTsnyYZlnIOquFIlMr5lOuGAwqyASpzLZxWeCLIweYaVw6AdYdqeNftx9RmcmZIwcB_NaFxiKIb8uBa2hpj9cDNnc7NkOlVTJvxiOHml93HtrnhGUSVaT9saYEkN0SBUfG0gja6KWh1g2w_UJQSmYk-TwlvofnbcHxpWR75DXDMLZgnWaiLpqgXn-4Y4auSvpLAO0RKafj5nOKN3dLwvnGSA8DlNQVZBnVjo.GFOmCeMoaLt8UJWAJLOKaRXhmZns8J1U1u9DSpERx-A&dib_tag=se&keywords=6000-2rs%2Bbearing%2B10x26x8%2Bsealed%2Bball%2Bbearings&qid=1737798941&sprefix=6000-2RS%2B%2Caps%2C175&sr=8-4&th=1

Place the bearing inside of the spinner. It should be a snug fit. If it’s a little loose (all bearings aren’t made with the same degree of precision, unfortunately) you can wrap a little Scotch tape around the bearing and trim it then push the bearing in. We’re not pulling G’s at the Nurburgring here so it won’t be making any high RPM’s. Push the spinner assembly firmly onto the upright shaft until it seats firmly. It should be firm enough for the shaft to rest snugly in the center of the bearing.

F3d files are included for remixing.

Heart-Shaped Cake Jewelry Box - Vintage, Kitsch Cake Container and Gift Holder

pixelandpapier__heart_cake__bottom.stl

pixelandpapier__heart_cake__AMS.3mf

This box was born as a special collaboration between me and [3D Printing World](https://thangs.com/designer/3dprintingworld), where I sculpted the Magnolia flower on top and he designed the mechanical box.

This box is an outcome of a special request for a marriage proposal of a great member of the 3D Printing Community.
**Caleb**, the producer and costar of [HotMakes](https://youtube.com/@HotMakesLive?si=8Z-TZeVbEQwuodcW) wanted a mechanical ring box that somehow incorporates his girlfriend (now fiancés) favorite flower, the magnolia.
- - -
This type of mechanism **3D Printing World** created is perfect for a magnolia since the number of petals on the flower line up perfectly with 60 degrees.
Each of the six petals on top are connected to an outside ring gear and an inside torsion loaded spring gear.
When you hold the box and rotate the ring gear the pedals open. When you let go of the gear, the spring loaded gear forces the pedals to come together.

_**The bottom of the box prints in place.**
Use a .4mm nozzle and .2mm layer heights or smaller. You will need to print three double pedals and three single pedals. You will also want to print the shim which will help to glue the pedals squarely onto the shafts. None of the parts require supports. **There is also 3MF files for dual color pedals.**_

_The top petals glue onto locators on the top of each shaft to glue it together.
Make sure you alternate between single and double pedals.
**See the assembly video for assembly instructions.**_
- - -
Much thanks to **3D Printing World** for creating this brilliant and magical mechanism that makes the box so unique, without which the magic would not have been possible.
