What it does

Simple to start, serious when you need it

As easy as Tinkercad, with a few big steps towards Fusion 360. Made for people who print what they design.

Offline and private

No account, no cloud. Your designs are saved automatically on your computer.

Exact CAD geometry

Chamfer and fillet edges, hollow out bodies, sketches with exact measurements, threads, patterns.

Exchange with other programs

STEP, STL, 3MF, OBJ and SVG in and out. Use it before Bambu Studio, Orca Slicer or Fusion.

Made for printing

Profiles for about 220 printers, overhang warning and a filament estimate.

Works with an AI helper

Connect Claude through MCP and let it build or change the model together with you.

Your language

Slovenian, English, German, French, Dutch, Polish, Czech, Hungarian and Russian.

About this version

Who makes what

Layerling is an open-source 3D modeling program by Stefan (henmedia), licensed under AGPL-3.0. It runs in the browser.

Cassette Deck Service builds the desktop version around it: a program you install, with automatic saving, a shared folder, a connection for AI helpers, custom fonts and Slovenian first in the language list.

The original Layerling is not our work. All credit for the program itself goes to its author.
