You can 3D print many different types of functional parts, including compliant mechanisms, gears, and rack and pinions. Another surprisingly printable type of part is hinges.
Hinges are great for making opening doors, containers, bag clips, chain links, and more. There are all sorts of different hinges for different applications, and 3D printing enables you to create custom-fitted parts that are perfect for your projects.
Hinges, even print-in-place options, usually comprise three main components, including the two articulating pieces and a pin. The former rotates around the latter to create a door-swinging-like motion. 3D printing allows you to create print-in-place hinges that don’t require any assembly, but these are more challenging to print.
Living hinges are another type of 3D printable hinges that aren’t like typical mechanical hinges; they’re thin sheets of material that can bend to function as a hinge.
Here, we’ll present the best 3D printable hinges, including both universal hinge designs and parts featuring hinges. Before we get into the models, though, we’ll first review some considerations to help you determine which hinge design is best for you and how to print it right.
There are many different considerations when it comes to choosing and 3D printing a hinge. In this section, we’ll go over a couple of important factors to think about.
Before you get to printing, you need to think about the 3D model:
Once you’ve picked out your model, you’ve got to print it. As hinges have multiple moving parts, 3D printing them is more difficult because all of the parts have to work together smoothly.
Now that you understand some factors to consider about 3D printed hinges, let’s get to the options!
In this section, we’ll go over a few models of open-use hinges that will work in many cases or can be customized to fit your needs.
This hinge follows a very standard design, making it very versatile. The hinge has two screw holes on each side piece, allowing you to securely mount the hinge for many applications, like a cabinet door. The original hinge measures 40 x 40 mm in area, but the designer notes that you can scale the hinge up or down, and no issues should occur.
The creator of this hinge design suggests printing the hinge with the side pieces perpendicular to the build plate to make the motion of the hinge smoother. They also recommend printing the hinge in PLA or PETG rather than ABS or nylon because the latter two materials are too flexible. A maker on Thingiverse listed that they printed the hinge with a 50-100% infill density and a 0.2-mm layer height with no supports.
Designed in OpenSCAD, this parametric hinge is a print-in-place option that follows a pretty basic structure. This hinge is very versatile because you can adjust a few different elements of the design, such as the size and number of mounting holes on the hinge, through Thingiverse’s Customizer app. Customizing your hinge allows you to make the hinge fit any of your needs and work with any hardware (e.g. screw size).
While not every customized hinge design (found in the Remix section) is the same, they’re all very similar, so the same print settings should work for most hinges. One maker posted a great image of their customized hinge and listed settings including a 0.15-mm layer height and a 20% infill density with neither a raft nor support structures.
This is a set of two hinge models that can easily link together to form a functioning hinge. While a few seconds of assembly is required for this option, this design may be easier to work with if you’re having problems with the print-in-place designs. You may also find this hinge useful in some situations because the two side parts of the hinge form different shapes (one is long and one is wide, forming a “T” structure when joined).
The creator of this modular hinge listed that the print took almost an hour and a half, consuming around 8 grams of filament. They also mentioned that they printed the hinge in PET filament, using a 0.15-mm layer height.
This remarkable hinge has a unique design consideration that sets it apart from the rest: it minimizes the risk of dust and debris hampering the operation of the hinge. With careful attention to detail, the designer has ensured that there are very few openings for unwanted particles to infiltrate the hinge. Say goodbye to the nuisance of debris obstructing the hinge’s functionality!
For this design, the author has mentioned the fun flexure of the hinge. Its design is not difficult to print and you can notice that its flexibility is its special feature, which makes it stand out from various other hinge designs. Users who have printed this model are sharing their positive experiences with this model, and some have also mentioned their attempts to execute the design with PLA and PETG filaments.
This sliding hinge is a special type of hinge that allows one of the side pieces to extend before the hinge pivots. According to the designer, this was done to enable the hinge to have more clearance to swing. The hinge is pretty thin, can open a maximum of 90 degrees, and, of course, prints in one piece.
The designer printed the model with a 0.16-mm layer height and used a 30% infill density. They also stated that they printed the hinge in PLA and used neither a raft nor supports.
This reversible hinge is a remarkable design that offers a wider degree of freedom by allowing the side pieces to swing in both directions. The hinge works by having two pivot axes (one for each side piece), so it’s almost like two hinges in one. The design was remixed from another reversible hinge design but added screw holes to allow you to mount the side pieces to other panels, like a door.
Although the designer didn’t include any printing tips, one maker showed off a great print of the reversible hinge and listed a few of their own settings: a 0.2-mm layer height, 30% infill density, no supports, and no raft. They also listed that they printed the hinge in PETG filament, which makes sense given this material’s rigidity.
This model is highly robust and dependable, offering a secure and seamless mechanism. It consists of two precisely fitting parts that create a harmonious connection when fastened with a reliable bolt or screw, resulting in a convenient hinge that enables effortless rotational movement.
Its versatility makes it suitable for a wide range of applications, including cabinets, wardrobes, armoires, and bookshelves. However, it’s essential to ensure proper alignment when attaching it to a surface, something that can be accomplished easily as the design can be customized according to the specific application requirements.
Bolt hinges are known for their exceptional reliability, withstanding significant shearing forces and exhibiting satisfactory performance when subjected to axial stresses. The design employs a transition fit, allowing the bolt to snugly fit into its designated hole with minimal pressure. This feature helps maintain the hinge’s concentricity. Therefore, it is crucial to adjust the tolerance of your prints based on the chosen bolt size.
The designer included the reference for the connecting screw bolt (M8 x 30 mm) in the pictures, although any changes to the size of the model (for example, scaling it up) might mean a different bolt. Overall, this model is straightforward to create and offers various potential uses to suit your specific needs.
This hinge mechanism is designed to resemble the wings of a butterfly and can be used in woodworking, cabinetry, or other applications where a decorative hinge is desired. It has two parts that are joined together with a pin or small rod.
You can use this beautiful design for decorative purposes such as on the door of your child’s room, or you can use it at an event or birthday party where you decorate your whole room. Its compact design makes it material efficient.
You can scale this model depending on the desired application, however when scaling, remember to resize the pin holes to the appropriate size for the pins as well.
In this section, we’ve listed a few popular designs that include integrated hinges but aren’t super versatile. These designs are great showcases of how 3D printing can be used to integrate hinges into designs easily.
Managing the elusive MicroSD and SIM cards can be quite the challenge! These minuscule storage wonders have a knack for disappearing or meeting untimely ends, thanks to their petite size. However, fear not – it’s high time we bring some order to the chaos and organize these precious MicroSD cards.
Introducing this sleek, tailor-made case to cradle your tiny MicroSD cards, shielding them from the perils of dust and pesky scratches. With this nifty creation, you can gallivant around with your valuable storage companions without an inkling of worry.
The design includes the pins already in the hinge holes, so that the hinge mechanism is integrated into the base and cover of the case, allowing the rotatory motion of the case. Because of the way the model has been created, a little force may be needed to release the hinge after you’ve finished printing it. The author has provided three versions, recommending the 0.4-mm and 0.5-mm options for those whose printers don’t have the best tuning. No more playing hide-and-seek with your digital treasures; this ingenious solution has got you covered!
After opening a bag of chips, bread, or similar food items, it’s best to keep the bag closed to ensure no air causes the food to go stale. While many people use the classic bag-roll method, a bag clip is more effective and reliable for keeping air out of your food bags.
This 3D printable bag clip uses a hinge mechanism and a notch at the end to keep the hinge latches shut on a bag. You can choose from three available sizes (65, 85, and 125 mm) to ensure the clip fits on your bag.
While the designer didn’t provide any printing tips, one maker printed the design with a 40% infill density and a 0.2-mm layer height.
This simple yet elegant hinge easel can be used for displaying photos, cards, mobile phones, or tablets. This could be very useful to decorate your house or other locations.
The designer chose a 33% infill, ensuring efficiency in material usage. While the designer suggests printing the model with a vertical orientation, other makers have been able to demonstrate a successful print while the model is oriented sideways, indicating it can be printed horizontally as well.
One of this model’s key advantages is that it can be printed as a single part, allowing for easy production. Additionally, its compact size makes it compatible with mobile phones, serving as a stand for both phones and iPads.
Designed in Autodesk Fusion 360, this parametric box is another great design with a hinge. The container can be opened and closed using its hinged lid, making it great for storing small items like keys or a wallet. You can also follow the guide (or download the available F3D file) to make your own box or adjust its parameters.
A community maker posted a great print of the box and listed that they printed the model on an Ender 3 in PLA, but beyond that, no print settings have been shared.
You might need customizable cases for your various possessions that have different sizes and measurements. Here, you will find a way to create bespoke cases for your items as the design can be modified depending on what you want to keep.
Unlike most designs on this list, this is a living hinge that allows repeated flexing without breaking or experiencing significant fatigue, and it benefits from flexible material to allow for movement.
The designer opted for a type of PET, but if you intend to use a less flexible material, such as ABS or PLA, they recommend that you modify the hinge and make it longer or thinner as needed to cater to the flexibility difference.
Hanging up clothes isn’t the most fun activity in the world, but it does help keep your closet (and the rest of your bedroom) organized. This folding coat hanger is composed of eight 3D printable pieces, features two integrated hinges, and can fold up into a small package that’s easily portable.
The designer suggests printing the hook for this hanger with a 0.1-mm layer height and 2-mm brim but without supports. Similar settings are recommended for the other parts but with a different brim width. One maker successfully printed the design in PLA using a 0.16-mm layer height and a 20% infill density.
This Raspberry Pi Zero case is a great way to house your mini computer board while testing your 3D printer’s capabilities, and it features two hinges that allow you to open and close the lid to access your Pi board quickly. The design has holes for the Micro-USB and HDMI ports, the MicroSD card slot, and even an opening for a Pi camera.
The designer listed that they printed the case with a 30% infill density and used a “medium” resolution, which probably means around 0.2-mm layer height. They also stated that they used no supports and that the case can be printed in any material.
Cable chains are a great way to organize your wires on a 3D printer, computer setup, or another environment with many wires. The underlying mechanism on many cable chains is hinges that connect each chain link and allow them to move up and down slightly to bend with the flow of the wires. You can print as many chain links as you want, and their small integrated hinges should snap together.
Although the design’s creator didn’t list any printing advice, one maker noted that they printed the design in PLA with a 65% infill density, a 0.2-mm layer height, and with supports activated but no raft.
