The 10 Best STL Files of 2025

Another year, another wave of STL files that are genuinely worth printing. In 2025, designers moved past the usual desk toys and figurines and leaned into designs that solve real, everyday problems. This year’s list has a bit of everything: a bird feeder that sends photos straight to your phone, a towel hook that uses gravity instead of clips, a chair that folds into itself like a piece of luggage, and yes, a massive dune buggy for anyone brave (and patient) enough to take it on. Whether you’re printing something practical or just want a project that shows off what your printer can really do, these are the STL files that stood out to us in 2025.

1. Smart Bird Feeder

This 3D-printed bird feeder blends backyard wildlife watching with smart technology, turning a simple print into a connected way to see exactly who’s stopping by for a snack. The design integrates a compact Wi-Fi camera directly into the feeder, capturing photos and video when birds land and sending them straight to your phone. It prints without supports and is intended for outdoor use with weather-resistant materials like PETG. A removable top lid simplifies refilling, while translucent parts make it easy to check seed levels at a glance. Several perch options are included, including an external version that positions birds slightly farther from the lens for clearer images. The feeder supports multiple popular camera models and can be mounted on walls, poles, or flat surfaces. The STL file is available here.

2. Giant Stacking-Block Dune Buggy

This oversized dune buggy is a bold 3D-printable tribute to a classic 1980s brick-built vehicle, reimagined at five times its original size. Rebuilt in CAD and released as a multi-part STL project, the model is designed for large-scale printing and hands-on assembly. Best suited for experienced makers, the build involves printing numerous components, fine-tuning part fits, and assembling the buggy post-print. Most parts are intended for PLA, while the tires can be printed in flexible TPU for a more realistic finish. Optimized for larger scales, the files are not recommended below 2.5×, with the provided versions already set to 5×. For makers who enjoy technical builds, mechanical detail, and a dose of nostalgia, this giant dune buggy offers a challenging yet highly display-worthy print. The STL files are available here.

3. Portable Chair with Storage

This looks like luggage, right up until it becomes something you can sit on. Built for portability, the chair stores all of its parts inside the seat itself, with the legs tucked away like a compact case. Opening it reveals a simple assembly process, with the legs locking into place underneath and extending via a snap mechanism. Once assembled, the chair supports up to 90 kg and can be carried by hand or with a strap when packed away. Printed in PLA, the design shows how 3D printing can turn mechanical ideas into practical, everyday objects. The STL file is available here.

4. Air Slides

Designed for warm weather and everyday comfort, Air Slides are fully 3D-printable summer slippers focused on breathability and ease of use. Optimized for flexible filaments like TPU, the design features a ventilated insole that promotes airflow and reduces heat buildup, paired with a lightweight infill sole for cushioning without excessive material use. A mesh-style strap adapts naturally to the foot while maintaining flexibility and ventilation. Printed as a single piece with no additional components required, Air Slides include clear sizing and scaling guidance to help achieve a comfortable fit. The STL file is available here.

5. Soda Can Opener

Simple, practical, and easy to print, this 3D-printed soda can opener makes opening beverage cans more comfortable and accessible. It works with both beer and soda cans and is printed in multiple parts that are assembled after printing. PETG is recommended for added durability, though the model can also be printed without supports depending on your printer setup. A clear assembly video is included, making this an easy everyday print and a thoughtful, functional gift. The STL files are available here.

6. Mini Whistle

Small in size but big on performance, this ultra-compact mini whistle delivers a powerful sound while using very little material. Weighing just 0.6 grams and printing in only a few minutes, it produces an alert sound of around 100 dB. That makes it a practical addition to a keychain for everyday carry. Suitable for emergency situations, outdoor activities, or personal safety, the design balances efficiency, loudness, and print speed. A great example of how smart design can turn a fast, low-material print into a genuinely useful object. The STL file is available here.

7. Tiny Dragon Egg Box

Small, detailed, and undeniably fun, this tiny dragon egg box turns a simple container into a playful 3D-printed object with real personality. The lid opens on a hinge and snaps shut, staying sturdy even when printed in decorative filaments like silk PLA. Assembly is hands-on, using a short piece of filament as a hinge pin and requiring a bit of care when removing supports. Whether used as a small storage box, a party favor, or a decorative print, it’s a lighthearted model designed for everyday handling. The STL file is available here.

8. Self-Watering Seedlings Pot

Designed to simplify seed starting, this self-watering seedlings pot keeps young plants hydrated during their most sensitive phase. It uses a standard water bottle as a reservoir, slowly supplying moisture over time. That makes it especially useful for herbs and vegetables that need consistently damp soil, such as basil, lettuce, or chili plants. Printed in PLA or similar materials, the pot is easy to produce and has been tested at low infill levels without leakage. A half-liter bottle can provide water for several days, cutting down on daily checks. Ideal for windowsills or countertops, this practical print supports healthy early growth before transplanting. The STL file is available here.

9. Toothpaste Squeezer

Designed to improve on common tube squeezers, this ratcheted toothpaste squeezer offers a simple and reliable way to get the most out of everyday toothpaste tubes. The built-in ratchet mechanism prevents the tube from unwinding once tightened, keeping pressure consistent during use. Made up of just four parts that click together without glue, the design is easy to assemble and stays intact when swapping tubes. It prints without supports and is sized to fit tubes up to 55 mm wide, with a horizontally printed shaft to improve durability. A small but practical print that turns a daily habit into a more efficient routine. The STL file is available here.

10. Towel Hook

This towel hook solves a small but familiar problem: towels that won’t stay put. The design is simple, but the way it works is what makes it interesting. You slide the towel into the slot and let gravity do the work, locking it in place without clips or springs. Lifting the towel releases it again. The hook prints as a single piece, with the moving element already enclosed, so there’s no assembly required after printing. Its ribbed finish gives it a neat, understated look, and it can be mounted with either screws or adhesive tape. An easy, everyday solution that fits naturally into bathrooms, kitchens, or workspaces. The STL file is available here.
