Romantic STL Files to Celebrate Valentine’s Day
Most likely originating in ancient Rome, Valentine’s Day is a celebration of love, celebrated, as you know, on February 14. So, we’ve put together some ideas for STL files that you can 3D print at home. Whether it’s for your significant other or just to try out some new ideas, here is a selection of original 3D models to celebrate love. From hearts to jewelry, flowers and decorative items, you won’t be disappointed! The various files can be downloaded from Cults, Thingiverse or MakerWorld. Some are free, others require payment. Happy Valentine’s Day to all!
A Locked Love Ring
Jewelry is a must for Valentine’s Day! And this year, we suggest that you 3D print a ring symbolizing eternal love. It was designed by Cults user Fischfluous in two parts, and the two intertwined hearts actually represent where the ‘braid’ of the ring is unravelling. Interestingly, the creator originally began creating it as an engagement ring, before it became this special creation. The STL file is available from $9.87 on Cults and was designed for a size 7. And if you aren’t keen on rings, the designer has also made other 3D models of jewelry, including a ‘three hearts’ necklace, so you can pick your perfect design.
A Heart-Shaped Bookmark
Would you like to give something more original than roses and chocolate? If you have a 3D printer at home and your partner is a book lover, why not try a bookmark? This 3D file of a heart-shaped bookmark will help readers keep their place. The 3D model can be printed in one piece using any color filament, although red or pink might be the most suitable. It weighs 2 grams and measures 70 x 75 x 2.5 mm. A practical and simple gift that you can 3D print for this Valentine’s Day!
Heart-Shaped Lockable Box
If you’re looking for a cute and practical gift for a loved one, this heart-shaped storage box is a great option. Perfect for storing precious keepsakes or jewelry, it looks right at home on a bedroom shelf or dresser. As the creator notes, the box is designed not just as a gift but for everyday use as well. One standout feature is the printable key, which lets you keep your belongings securely stored. The box and key files are available separately, both for free on Cults. The uploader, PA1_MAKER, also provides detailed recommendations for optimal print settings, so be sure to review those before printing. Enjoy!
Mr. and Mrs. Egg Cups for Valentine’s Day Morning
Healthy breakfasts can be perfected with these egg cups for him and her! Ideal for boiled or runny eggs, these cups will brighten up your mornings, and what’s more, the file is available for free. The STL file is from Formbyte, a well-established creator on Cults. Printing with ceramics is recommended, but resins are also possible. Of course, these egg cups can be used all year round. It’s truly unique, and not something you will find in the supermarket!
3D Printed Flower Kit
Next on the list is a flower building kit, perfect for gifting or enjoying the experience of assembling it with someone special. The set includes petals, leaves, modular stems, and everything you need to assemble the floral arrangement. There are seven different flower designs, which can be combined and customized to suit your style. The leaves have embossed veins, allowing for a color change in the outer layers that highlights the details and adds realism to the design. In addition, the flowers can be printed in any color or painted with acrylic spray paint to achieve other color gradients, as recommended by the model’s creator.

A Romantic 3D Candle Holder
This delicate candle holder with hearts that let the light shine through is a piece that transforms any space into a warm and romantic corner. It is printed with an FDM machine, using PLA and without the need for supports, so at the end of the printing process, you just need to remove it from the plate and place a candle inside. The author of the 3D model recommends a layer height of 0.2 mm and a fill of 17% so that the piece can withstand moderate use with candles. As for the colors, the author programmed a color change on layer 90 to achieve a Scandinavian design. What colors would you print this candle holder in for Valentine’s Day?

A Heart Pendant
Add some fun to your Valentine’s Day outfit with this 3D printed heart pendant! This pendant could be used for a necklace or printed twice to create a pair of earrings. This model is optimized for 3D printing and is designed to have smooth curves. It consists of two interlocking, flat hearts that can be attached with some glue. Because they’re flat parts, this part would be easy to customize by painting a design on the surface before assembling the pendant.

Love Frame
This 3D printed “Love” frame, paired with a favorite photo, makes a thoughtful last-minute Valentine’s Day gift. The model is available in three sizes (standard, large, and very large), with the standard version printing in under two hours and the very large in just 2.3 hours. To fit the frame, the photo needs to be cut into a heart shape. And here’s a tip: use the second heart plate included in the model to trace the outline on your photo before cutting for a clean, precise fit. Lightweight and easy to display, this frame works well on desks, shelves, or bedside tables and makes a personal gift for someone special.

Hearts to Hide Around the House
Here’s an original game to play on Valentine’s Day! We suggest you 3D print 100 little hearts and hide them around your home. The goal? For your significant other to find them as quickly as possible! Each heart is numbered to make the search easier. You can choose the material you want, as well as the color: feel free to mix it up! Different layer thicknesses are available, with more or less dense filling depending on the hearts you want to make. The STL file is available on MakerWorld. This little game of hide-and-seek can be played on any occasion. Have fun!

For optimal results, the recommended settings include a 0.2 mm layer height, two walls and 15% infill. The best part? The model prints in just over an hour, making it a quick and easy last-minute gift. Whether you’re new to 3D printing or a seasoned maker, this small but sweet keychain is the perfect project to spread a little love with every print.
