Why makers like it

Made for a clean first print

Every room, one style

Print a matching set of signs in a single evening. No CAD, no supports, and each one slices clean.

Ready for rentals

Set up room numbers and a welcome sign in minutes. The STL slices with zero repairs, so it just prints.

Size it before you print

The live 3D preview gets the dimensions right the first time, so you print once instead of twice.

Print tips

Get a clean print, first try

PLA for indoors

Easy to print, every colour. For sun or outdoors, switch to PETG or ASA for UV and heat resistance.

No supports needed

Every model exports flat-side-down with its base at z=0, so letters print straight up off the bed.

Watertight STL

Each export is a manifold mesh that opens cleanly in Cura, Bambu Studio, or PrusaSlicer, with no repair step.

FAQ

Frequently asked questions

What can I make with Extrudo?

Anything text-based: door and room signs, name plates, house numbers, keychains, cake toppers, and gifts. Type your text, shape it in 3D, and download a print-ready STL.

Do I need supports to print?

No. Every model exports flat-side-down with its base at z=0, so the letters print straight up off the bed with no support material.

Is the STL ready to slice without repair?

Yes. Every export is a watertight, manifold mesh, so it opens cleanly in Cura, Bambu Studio, or PrusaSlicer with no repair step.

Can I make a two-color print?

Yes. Add a backplate and export the colour 3MF for Bambu Studio. The text and plate come through as separate coloured parts, ready for the AMS.

What filament should I use?

PLA is ideal for indoor signs: easy to print and available in many colours. For outdoor or sunny spots, PETG or ASA resist UV and heat better.

Does it cost anything?

The tool is free with unlimited downloads and 4 fonts. A one-time $5 Pro unlock adds 40+ premium fonts and special backplate shapes, with no subscription.
