Fresh flowers will be gone by March, but a 3D print can last for years.

Whether you need a romantic gift for your sweetheart or a cute heart-shaped toy for your kids, we’ve got you covered with these 11 Valentine’s Day 3D Prints. We’ve selected a variety of models that are easy to print and fun to display.

Gifts should come from the heart – and a highly tuned FDM printer! Make sure your 3D printer is in excellent shape with these tips for new makers. Load up some sparkly red filament, like Protopasta’s Candy Apple Red Metallic (opens in new tab), and you’ll be ready impress your Valentine with a homemade gift.

If you’re printing toys for small children, remember to always supervise play. PLA is easily broken and could become a choking hazard. 

Unless otherwise specified, all printing times are based on Cura 4.12.1, using a standard profile with a .2mm layer height, 50mm print speed, on a Creality Ender 3 Pro which sits at the top of our list of best 3D printers. Your results may vary.  

Rose

We searched high and low for the perfect 3D printed rose and this was our favorite. It’s fairly life-like, easy to print and it comes complete with a stem and leaves. Most importantly, the flower prints without support, which means the petals don’t need to be cleaned up. You do need support on the leaves. We recommend printing them on edge with a raft for extra adhesion. 

You’ll need to plan ahead if you want a dozen of these, so get started now.

Why do we love fidget toys so much? We don’t know, but this Heart shaped fidget will have your Valentine mesmerized. The file has three versions – a simple three layer heart, another with six or the super nine layer fidget supreme. 

We printed this heart in dual layer Quantum filament for even more satisfying eye candy.

It’s a trap! I know. B Mine Will U. 

Tickle the fancy of your favorite Star Wars nerd with these 3D printed Conversation Hearts. There are 24 sayings in all, with tiny quotes covering all the movies plus the Mandalorian streaming show. 

We printed our hearts with a filament swap to get two colors, but they’re just as cute in a single color. No time for swapping? It’s quick work to add a touch of white paint to the letters after printing. These are super fast prints, so go ahead and make them all.

Lovely Fidget

This fidget toy relieves stress while reminding your Valentine how loved they really are! There are 4 patterns to mix and match. The toy rotates from oval to heart and back again on a 3d printed post.

It can be made super snappy with the addition of magnets glued next to the pivot point. Holes for 6mm and 3mm magnets are built into the design, but we scaled our print up to 135% to fit some 8mm magnets we had on hand. 

The Lovely Fidget is based on one of 3D Printy’s puzzle boxes. If you’re up for a challenge, you can find the box version here.

Fill this elegant filigree box with candy or another sparkly gift. The box needs no supports and prints best with the lid face down on a smooth glass or PEI build surface.

The first version of this box has a solid lid if you want to keep the contents a secret.

Does your Valentine love brain teasers? This puzzle has 16 shapes that fit into the heart base 363 ways. Best of all, a solution to the puzzle is etched into the back of the print, in case you need a hint.

These tiny puzzle pieces require a super clean and level bed. We had to reprint the heart base at 105% to get everything to fit well.

This optical illusion is amazingly easy to print and is completely support free. It’s designed in two pieces – a tower of flowing hearts and a bucket. The bucket doesn’t need glue, just balance it on top of the pile.

We scaled our print down to 65% for faster printing.

Maz’s Flower

3D printing a realistic rose is harder than you think, but Maz’s Flower is pretty close. We’ve printed a lot of flowers looking for the best one, and though this is not a realistic rose shape we like it a lot. It prints in a few hours without any support, another big win in our book.

The flower comes in three parts: a flower and both upper and lower leaves. There is no stem to print, but you can use bamboo skewers painted green. We printed our flower at 85% to save more time.

It’s a vase! It’s a cup! It’s a tealight! This heart shaped vase is a fun print with many options and sizes to choose from. You can print it solid, in vase mode, or in two parts for extra color.

This is a paid file at Cults, but the designer has included over a dozen variations to pick from. We printed the “full hearts 4 rings” at 65%, then printed an insert in vase mode.
