Ez3D is the dead-simple way to make real, printable parts — brackets, knobs, threaded bolts, custom mounts — right in your browser. Plain language, no learning curve.
No sign-up. · Works offline. · Nothing leaves your computer. · Exports clean STL & 3MF for Bambu, Prusa, any printer.
Why Ez3D exists
Most 3D apps are either too basic to make functional parts, or so complex you give up before you start. Ez3D is built for the gap in between.
Fun for blocks and name tags, but no real threads, no precise sizing, no print checks. You hit a wall fast.
Type the sizes, pick a template, cut a hole, add real threads, check it'll print, export. Functional parts, minutes not hours.
Powerful, but a steep cliff of menus, constraints, and tutorials — overkill when you just need a bracket that fits.
What you can make
Start from a shape or a ready-made template, then make it yours with simple, plain-language tools.
Nuts, bolts, threaded rods, and tapped holes that actually thread together — with an adjustable fit gap.
Type every dimension in millimeters — or inches (just type "2in"). What you draw is what you print, 1:1.
Make a hole, glue shapes together, counterbore or countersink for flush screws. No "boolean" jargon.
Brackets, washers, standoffs, hooks, knobs, cable clamps, boxes with lids — adjust a few numbers, done.
Bring in an STL or 3MF and resize, cut, or build around it — even repair non-watertight scans.
A live readout flags parts too big for the bed, floating in the air, paper-thin, or overlapping — before you waste filament.
Hollow a part to save filament, round or bevel the edges, and repeat a shape in a grid or circle.
Click two points to measure distance and gap, or three for an angle — right on your model, in real time.
Autosaves as you go and restores your last session automatically. Export STL or Bambu's native 3MF.
How it works
Pick a basic shape or a template from the Add menu.
Set the dimensions in mm or inches. See the size update live.
Cut holes, join parts, round edges — then let Print check confirm it'll print.
Download a clean STL or 3MF and open it in Bambu Studio or your slicer.
