80+ editable shapes, shaping tools that go far beyond boxes, and checks that tell you a print will work before you waste filament. Free, in your browser.
Every shape keeps its settings, so a gear can get more teeth or a star more points long after you placed it.
Ten categories, from boxes and gears to symbols, parts and buildings. Search understands everyday words like “donut”.
How it works ›Raised or cut-through lettering. Load any .ttf or .otf, and write Hebrew or Arabic right to left.
How it works ›Set how many sides a round shape has, from smooth to low-poly, and chamfer or round its edges.
How it works ›Turn any shape into a hole and merge it into a solid, the classic way to cut slots, pockets and mounting holes.
How it works ›Make any shape hollow with a wall thickness you set, and open the top for a cup or pot.
How it works ›Every tool previews its result before you commit, and nothing changes until you press Apply.
Melt two or more shapes into one smooth piece, like clay, with the seams as soft or sharp as you want.
How it works ›Springs, knots, shells and lattices from maths, with 19 starting points to adapt to your own sizes.
How it works ›Curve a straight row into a ring, twist a vase, or narrow a part towards one end.
How it works ›Up to 200 copies along a line or round a ring, with an exact gap between each one.
How it works ›Add a rim to the top or base: a flat collar, a flare, or a rolled edge like a bin.
How it works ›Slice a model with a box you can move and turn, or take an imported model apart into editable shapes.
How it works ›Push or pull one flat face of an imported, cut or merged model to add or remove material.
How it works ›Line parts up, space them evenly, flip them, or square them to the grid in one click.
How it works ›Type exact numbers anywhere, and see exactly how far apart things are.
Snap steps from 0.1 to 10 mm, and plate sizes with presets for common printers.
How it works ›Show size, distance to the nearest parts, or margins inside what it sits on. Click a measurement to type a new one.
How it works ›See, select, move and cut parts hidden inside others, like a shaft in a housing or a magnet pocket in a lid.
How it works ›Size, position and rotation as numbers, with keep-aspect resize and a colour for every part.
How it works ›About 60 steps back, even after closing the tab or coming back the next day.
How it works ›Keyboard shortcuts, a view cube, orthographic view, full screen and panels you can hide.
How it works ›Built for the problems that actually ruin prints: parts that snap, parts that fuse, and parts too big for the bed.
Bend it in the computer first: does it spring back, stay bent or snap, in PLA, PETG or TPU?
How it works ›Lists every pair of parts that touch or come too close, so print-in-place parts come off the bed moving.
How it works ›Click a face and the part turns to lie on it, so the best side goes down on the bed.
How it works ›Cut it in two at exactly the right height, then lay each piece flat side down.
How it works ›Up to 64 MB. A 3MF keeps its objects and colours, and an SVG becomes a solid you can build on.
How it works ›3MF keeps separate, named, coloured parts for multi-colour printing. STL opens anywhere. Always in millimetres.
How it works ›Bring in a model from Thingiverse, Printables, MakerWorld and more, then resize it, cut it or add to it.
How to bring a model in ›Changes save to your account about a second after you make them, so your models are on any computer.
How it works ›Sign in with Google. Your models stay private unless you choose to share them, and twyk is free, with no plans or payments.
How it works ›Publish a model for everyone to see. Browse what’s trending or most recent, and like what you love.
How it works ›Copy any shared model into your own models, then resize it, add your name or make it fit your gear.
How it works ›Report anything that shouldn’t be there. Models several people report are hidden until a moderator checks them.
