Design, generate and prepare -
in one browser tab

A modeller, smart generators and a print-prep toolbox that work together, so the file you export is the one that prints.

01 / GENERATORS

Smart generators do the hard part

Type a link, pick a picture or set a few numbers - the model builds itself.

  • QR codes checked to scan, with logos, labels and NFC pockets
  • Name keychains, picture stickers, trays and Gridfinity bins
  • Jigsaw puzzles and flexis - with knobs and hinges you design
Try the QR code generator

DWGQR-01Scale1:1Sheet1 / 4
02 / ENGINEERING

Precise enough for real mechanisms

Exact millimetres, real involute teeth and fits you can trust - parts that work the first time.

  • Spur, helical, planetary, bevel and worm gears, checked to mesh
  • Sketches with constraints and dimensions, extrude and revolve
  • Holes with fit clearance, booleans, rounded edges and measuring
Try the gear generator

03 / PRINT PREP

Ready for the printer, not just the screen

Catch problems before they cost filament - and fix them in a click.

  • Overhangs in red, pillar supports, lay on a face, cut below the bed
  • STL and 3MF import, mesh health, make solid, reduce file size
  • Resize to the millimetre, cut big parts in two with connectors
Guide: reduce an STL file

04 / MULTI-COLOUR

Colour that makes it to the slicer

Paint faces, combine coloured parts and keep every colour through cuts and booleans.

  • Brush, fill a face or paint a whole part
  • 3MF with each colour on its own filament, for AMS and MMU
  • Lithophanes and HueForge-style prints from your photos

; LAYER 02 · WHO IT'S FOR

Engineers & tinkerers

Involute gears, Gridfinity to spec, custom puzzle knobs and print-in-place hinges you test.

; LAYER 06 · FAQ

Questions, answered

Do I need to install anything or make an account?

No. 3DPrintCAD runs in your web browser on a computer. Open it and start designing - there is no account and nothing to install.

Where are my designs saved?

In your own browser, on your computer. Nothing is uploaded. You can save a backup file of all your projects at any time and load it in any browser.

Which printers and slicers does it work with?

Any. It exports STL for every slicer and multi-colour 3MF that opens in Bambu Studio, OrcaSlicer and PrusaSlicer with each colour on its own filament. Pick your bed size from the common ones (180 to 350 mm, 256 × 256 by default) or type your own.

Is it good for kids and beginners?

Yes. You build with shapes like building blocks, and the generators make keychains, stickers and puzzles in a few clicks. Pros get exact sizes, sketches with constraints, mesh repair and multi-colour export.

Does it work on phones and tablets?

The editor needs a computer with a mouse - 3D design on a small touch screen is no fun. This page and the guides work everywhere; send yourself the link and open it on your computer.
