twyk vs Layerling: Browser 3D Modelling for 3D Printing Compared (2026)

At a glance

	twyk	Layerling
Best used for	Getting from “I need this” to a part that prints: build it from shapes, size it to the millimetre, check it prints	Hobbyists outgrowing Tinkercad who want more CAD-style precision
How you build	Drag & drop shapes and holes; then Sculpt, Formula and Bend	Shape manipulation with quick-click tools, plus sketches extruded, revolved or swept
Learning curve	Low	Low to medium
Cost	Free: no plans, payments or subscriptions	Free and open source
Account and storage	Sign in with Google; models save to your account as you go	No account: designs stay in your browser, or on your own server if you self-host
Fillets and chamfers	Bevels and chamfers on round shapes (cylinders, cones, tubes and more)	On any edge, changeable later
Threads	No dedicated thread tool (springs and coils via Formula)	Metric, UNC/UNF and Whitworth threads on screws, nuts, rods and tapped holes
Organic and mathematical shapes	Sculpt, Formula (19 presets), Bend/Twist/Taper	Lofts, springs and gears in the shape library
Print checks	Flex test (PLA, PETG, TPU), Gaps clearance check, Lay flat, Cut big models in two	Build-plate and overhang warnings, weight and filament estimate
Import	STL, 3MF (with colours), SVG, up to 64 MB	STL, OBJ, 3MF, STEP, SVG
Export	STL, 3MF (named, coloured parts)	STL, 3MF, STEP, OBJ, SVG, plus workshop drawings

Compiled in October 2026 from Layerling’s own website and help pages, and twyk’s help guide (sources below). “Not built in” means we couldn’t find it as a standard feature. Layerling is made by the Layerling project; twyk is not affiliated with it. Spot something out of date? Tell us.

✓ Choose twyk if…

You want organic shapes (Sculpt) or mathematical ones like lattices and knots (Formula).
You want your models saved to an account and available on any computer.
You want to test flexible prints and check print-in-place clearances before printing.

Choose Layerling if…

You need fillets on any edge or real, standard threads for screws and nuts.
You need STEP export or workshop drawings for machining.
You want open-source software you can self-host, with no account at all.

Moving from Layerling to twyk

Export from Layerling as STL or 3MF and import into twyk. A 3MF keeps its separate objects and colours. From there you can cut it, add to it and resize it. See importing and exporting, or how to bring in models from any site.

What twyk adds

80+ shapes and 48 fonts, each with settings you can change later. See the shapes
Exact sizes in millimetres or inches, a ruler for gaps, and X-ray for hidden parts. See the precision tools
Sculpt, Formula and Bend make organic, mathematical and curved shapes. See the shaping tools
Flex and Gaps test flexible parts and print-in-place clearances before you print. See the print checks

Frequently asked questions

What's the difference between twyk and Layerling?

Both are free browser tools for designing 3D prints. Layerling focuses on CAD-style precision such as fillets on any edge, standard threads, sketches and STEP export, with designs stored in your browser. twyk focuses on easy shape-based modelling, organic and formula-based shaping, and print tests like Flex and Gaps, with models saved to your account.

Can twyk make threads?

twyk has no dedicated thread tool. You can make springs and coils with Formula, and if you need standard metric or imperial threads, Layerling is the stronger choice.

Is twyk open source?

No. Layerling is open source and self-hostable; twyk is a free hosted app you sign into with Google.
