About this generator

Modelador 3D Channel Letters & Signs is a free browser generator for 3D lettering, from the same small Brazilian modeling studio behind the Modelador 3D Part Generator. You type a text in one of about 15 fonts, from classic and display to themed styles, or upload a logo as an SVG with outlined curves, then pick a type: solid letters, hollow channel letters with walls and a back, front-lit letters ready to take an LED strip, or raised text on a plaque. You set the real letter height from 20 to 1000 mm, the depth, the wall and back thickness, and a flat, chamfered or rounded front.

Each letter comes out as a separate part in the STL, like a real shop sign, and a thin-stroke option thickens serifs and fine fonts that would otherwise fail to print. The page explains how to print channel letters back down without supports and says to use ASA or PETG outdoors. Letters larger than your bed are not split yet, and PNG or JPG logos, custom fonts and LED cable channels are listed as coming later. The interface is in Portuguese.

Downloads are free once you register a first name and email, and an optional donation is suggested. It suits makers who want a shop sign, house number or a light-up logo without modeling the letters themselves.
