15 Cool Things to 3D Print

Published on November 6, 2020 by Aysha M.

Once in a while we collect some of the best models to create with your desktop 3D printer. Usually we follow a theme, as it was the case with, for example, our recent list of Top 12 Halloween prints. This time around however, we wanted to present you all kinds of interesting models, so we have created a list of cool things to 3D print, where everyone can find something they are interested in printing. The ideas are divided into 3 categories: Useful things, decor, and for geeks. At the end of the short description of the 3D printable object you will find a link to download the digital file, mostly in STL format; some files are free but for a couple of them you might need to pay a small fee. Have fun!

Useful things

Kitchen containers

These are kitchen containers that can be used to store your coffee and sugar. Featuring the chemical structures of sucrose and Caffeine as part of their design, the containers might be a fun addition to your kitchen. They come with two types of lids – flip or push. Perhaps, you might want to print the push ones as they are better for coffee or sugar storage to retain the aroma or keep away the ants. The kitchen containers are 6.4×3.7×8.9 cm (sugar) and 6.4×3.4×7 cm (coffee). Don’t forget to verify that your 3D printing material is food safe. You can download the STL file HERE.

Bike coffee holder

The Coffee Cup Holder is a very practical accessory for your bicycle. The design looks very clean, and if you are the kind of person who loves coffee, then it’s a perfect idea for you to 3D print! The download includes files in 7 different sizes to fit a variety of bike frames. According to the creator of the bike coffee holder files, Harry Dalster, the approximate print time is 6 hours. You can download the STL file HERE. Enjoy the ride with your 3D printed gear!

Self-watering planter

Parallel Goods introduced their first design, the Self-Watering Planter. The planter is exactly the growing environment your plants need, while giving you flexibility in your watering routine. Designed to be 3D printed with PLA, the item is very easy to use: just plant your favorite herb or other water-intensive plant, add water, and you’re all set. You can customize your planter by mixing and matching different colors for the pot and reservoir. How does the self-watering work? Just set the pot in the reservoir, add your plant of choice, and fill the reservoir to the line inside of the spout. Then refill whenever you can’t see any water in the spout. The file can be downloaded HERE.

Pencil holder

Next in our list of cool things to 3D print is an item that will help you avoid mess on your desk, pen and pencil holder. The beautiful geometry of the holder caught our attention: the smooth lines remind of waves and the honeycomb-like structure, when looked at from the top, is always a nice visual addition. You can experiment with the color of your print to make the beautiful design reflect your personality. You can download the file HERE. Organize your workspace well and stay productive!

Combination Lock

The combination locks seem like a very useful idea. If you your suitcase lock is lost or broken, panic not! You can 3D print a new one, and then assemble the parts easily. To manufacture your own customized combination lock, you can start by choosing a size: 3, 4, or 5 digit passcode. The file is available HERE. Also at the link, the creator of the design explains the assembly process in detail. For instance, to fit the wheels into the slots, you need to place the two halves onto each other, and attach with either a M3x20 nut and bolt or superglue, and make sure not to get any glue on the wheels–you won’t be able to spin them if you do.



The decor category of our cool things to 3D print list, starts with a beautiful lamp inspired by the famous Eiffel Tower. The design was born from a collaboration between le FabShop, a 3D printing startup from Brittany, and Maison&Objet, an international furniture fair. Designed and engineered by Samuel N. Bernier, a canadian industrial designer, this object was produced using MakerBot Replicator Z18 desktop 3D printer. In the 3D file, the upper and lower parts of the 30cm wide lamp are cut into quarters. To print the entire lamp, you should print four times the bottom quarter and four times the upper quarter. Then you’ll have to clip each of these parts with each other. The model can be printed without any support, just use raft. You can download the file HERE.

A sophisticated addition to your interior design, this lamp is easy to 3D print and a treat to look at! It is a single contiguous shape at all layers, and can be printed with a single line of extrusion. That is, it’s a vase mode print. The Orbit Vase 2 digital file is available HERE.

Flower pot

The last two models in the decor category of the cool things to 3D print are for plant lovers! This particular collection is called Cute Girls Planter, and features four different designs, which will look very harmonious in almost any space. The digital files are available in three formats: .obf, .fbx, and .stl. You can purchase the file HERE.

Anti-gravity planter

This simple but at the same time unique planter is easy to 3D print and assemble. You will need to print two bases, which are responsible for the anti-gravity visual effect, without supports and assemble them with two threads, as shown in this video. As for the planter itself, print it with supports (they should be easily removable) and snap it into one of the two bases. The planter has no drainage hole, so there should be a layers of pebbles on the bottom in order to avoid killing the plant. The file to download is available HERE.

For Geeks
