Custom 3D printed house numbers
Type your address number, pick a bold font, and download a print-ready STL. Print large, weather-ready numbers for your door, mailbox, or gate.
Free to use · watertight STL · prints with no supports
Bold and readable
Set a large size and a thick depth so the numbers read clearly from the street. Preview the exact look before you print.
Mount any way
Print the numbers on their own to glue or screw to a surface, or add a backplate for a single mountable plaque.
Built for outdoors
Print in PETG or ASA for numbers that resist sun and rain. The mesh exports watertight so the print stays solid and weatherproof.
How it works
Design and download in seconds. No CAD experience needed.
1. Type it
Enter your text and pick a font. The 3D preview updates live as you go.
2. Shape it
Adjust depth, size, and bevel. Add a backplate for a mountable, two-color sign.
3. Download it
Export a watertight STL, or a color 3MF for Bambu Studio. It prints flat, no supports.
Questions
How big should 3D printed house numbers be?
For street visibility, aim for numbers around 100 to 150 mm tall. Set the size in the tool and preview it before exporting the STL.
What filament lasts outdoors?
PETG and ASA resist UV and heat far better than PLA, so they are the best choice for house numbers exposed to sun and weather.
Can I print numbers and a plate together?
Yes. Turn on the backplate for a single plaque, and export the color 3MF to print the numbers and plate in two filaments.
