3D printing continues to unlock incredible creativity. From practical household tools to artistic designs, makers around the world are constantly creating useful and beautiful models. Here are 10 impressive 3D printing projects that showcase just how versatile a 3D printer can be.
1. 8-Bit Mario Mahjong Set
This amazing “8-Bit Mario Mahjong” project replaces traditional mahjong symbols with pixel-style graphics inspired by the classic Super Mario universe.
The dots become gold coins, the bamboo tiles turn into green pipes, and the character tiles are transformed into power-ups and classic enemies. The level of detail from designer Angie's Gizmos is truly impressive.
The set includes all 144 playable tiles, flower tiles, dice, chips, and a large storage box that stacks into a giant “question block.” Each tile is printed in two halves so you can insert metal wheel-balancing weights, giving the tiles a satisfying, heavy click when played.
The design is optimized for multi-color printing on Bambu Lab machines, supporting up to four colors per plate—making it a perfect centerpiece for your next game night.

2. Zipper Repair Tool
A broken zipper often means throwing away an otherwise perfectly usable item—or paying a tailor to replace the entire zipper.
This clever 3D-printed zipper slider replacement solves that problem. The redesigned zipper head can snap directly onto existing zipper teeth, meaning you don’t even need to remove the zipper stop.
The V3 version addresses a common weakness in 3D-printed parts: layer adhesion strength. By printing the internal connector pin vertically, the designer significantly improves durability.
Designer MisterJ provides files for multiple zipper sizes, including versions for reverse waterproof zippers. With a well-calibrated printer, a drop of super glue, and a few minutes of assembly, your favorite item can be functional again.

3. Bathtub Caddy
Taking a long hot bath is relaxing—but balancing a tablet on the edge of the tub while holding a drink is just asking for disaster.
This 3D-printed bathtub caddy spans a standard 70 cm bathtub, keeping your relaxation essentials safe and dry. It includes:
- A rear slot for tablets or books
- A recessed drink holder
- Four extra compartments for phones, soap, or earbuds
Because a full-size tray won’t fit on most printers, the designer split the model into three modular pieces. After printing, simply insert 15 mm connectors and secure them with glue.
Pro tip: Print using PETG, which handles warm and humid bathroom environments better than PLA.

4. Retractable Tape Cutter
Struggling to find the end of packing tape or tear electrical tape cleanly is a common frustration.
The Masky Blade tape cutter clips directly onto your tape roll and makes cutting fast and effortless. This upgraded version features a retractable blade for safety and works with various tape sizes—from narrow electrical tape to wide packing tape.
The design is elegantly simple, consisting of only three printed parts:
- Main body
- Sliding mechanism
- Printed spring
No supports or additional hardware are required. It uses a standard utility blade or single-edge razor for clean cuts every time. The designer even includes left-handed and right-handed versions, and the latest update adds a tilted blade angle for smoother cutting.
Just watch your fingers—it’s sharp!

5. HydroSquare Rain Planter
If you want to add a touch of nature to your desk or bookshelf, the HydroSquare Rain Planter beautifully combines 3D printing, electronics, and plant care.
This 25 × 25 cm planter is designed for the Bambu Lab LED Kit 001, functioning as both a planter and an ambient lamp.
Its standout feature is a built-in rain irrigation system. Instead of watering the soil directly, you pour water into a top reservoir. The water then slowly drips down, simulating natural rainfall over the plant.
Under the LED lighting, the falling droplets create a beautiful visual effect while providing an ideal spectrum for herbs or succulents. The model also includes a hidden cable channel to keep wiring tidy, giving the finished piece a premium look.

6. Elysiar Vase
If you’re tired of the typical spiral “vase mode” prints, the Elysiar Vase offers something far more elegant.
This sculptural design focuses on flowing curves and negative space, making flowers appear as if they are floating in midair. The structure resembles a lyre, giving it the feel of a high-end design piece you might find in a boutique store.
The effect is achieved by holding a standard 15 mm glass test tube at the center of the frame. The glass provides waterproof functionality, while the printed frame allows complex shapes impossible with traditional ceramics.
It’s a perfect example of functional art created through 3D printing.

7. Customizable Spray Stencil
Creating spray paint stencils by hand can be tedious and tough on your fingers.
This customizable stencil generator automates the process. Using MakerWorld’s parametric model generator, you simply enter your text, choose a font, and generate a printable stencil—no CAD skills required.
Unlike fragile paper stencils, these 3D-printed versions are durable and reusable. The design includes a sturdy border that keeps the stencil flat and prevents overspray.
They’re perfect for marking toolboxes, shipping crates, storage bins, or adding industrial-style lettering to your gear.

8. Corner Desk Lamp
If your desk sits against a wall, you probably have a dark corner where pens mysteriously disappear.
The Corner Desk Lamp V2 solves this with a minimalist triangular design that fits neatly into the corner while casting soft indirect light onto the wall.
This updated version improves the original design with a two-part structure:
- A dark outer shell to block light leaks
- A white inner diffuser for smooth illumination
It’s designed for 10 mm LED strips (RGB or warm white), turning a forgotten corner into a cozy lighting feature.

9. Fruit Washer Bowl
Washing small fruits like blueberries or grapes can be tricky—you want to clean them thoroughly without losing half of them down the drain.
The Fruit Washer Bowl solves this with a clever combination of bowl and strainer. The updated design slightly reduces the drainage hole size so water first collects in the bowl, allowing the fruit to soak before draining slowly.
This ensures the fruit is actually washed instead of just rinsed.
The model prints without supports and has a 130 mm diameter, making it ideal for a single serving of healthy snacks. As with all kitchen prints, it’s recommended to use food-safe materials or limit contact time.

10. Toothbrush Travel Case
Traveling with a toothbrush usually means using a flimsy plastic cap that falls off or a zip bag that quickly becomes messy.
This 3D-printed toothbrush travel case offers a more durable solution. It’s designed to withstand bumps during travel while keeping the bristles clean and dry.
Instead of using fragile printed hinges, the design uses a clever low-tech solution: a piece of 1.75 mm filament acts as the hinge pin connecting the lid and base.
The result is a durable, easily repairable hinge that’s simple to assemble—just slide the filament through and trim the excess.
