Tired of juggling three apps, and designing in tools never made for artists?

Upload-and-trace apps are converters: you get an outline and not much else. Anything more considered means Illustrator for the drawing and CAD for the walls, and CAD was built for engineers, not for artists making statement pieces. This is a full vector studio and 3D workshop in one, made for the way artists work: draw it, trim it, repeat it, and build it as a print-ready cutter, stamp, embosser, stencil or roller. It costs more than a simple upload-and-trace tool because it replaces one. See exactly what’s different

The brush is the wall

Draw in the thickness you print.

In Fusion a line has no width. You sketch it, offset it to make a wall, close the ends and trim the overlaps before you can extrude anything. Here the brush is the wall: set your thickness, draw, and every stroke is exactly what prints. No more offset lines. Real vector drawing, with the brush Fusion never had.

In Fusion

Five steps before you have a wall

  1. Sketch a line
  2. Offset it
  3. Close the ends
  4. Trim overlaps
  5. Extrude

Five ways to make

One design, five tools.

Switch make-mode in a click. The whole design carries across, and each mode builds the right 3D part for you automatically.

Cutter

Sharp-bladed cutters with a solid base, inner imprints and score lines.

Stamp

Press stamps with a snap-fit handle, your design raised or recessed on the face.

Embosser

Relief plates that leave your motif pressed into the clay surface.

Stencil

Cut-through stencils for painting, texture paste and layered work.

Roller

Textured rollers with seamless, endlessly repeating pattern tiling.

In the box

01

Real vector drawing

Pen, freehand and full bezier curves, node editing, a live shape library and corner styles with a radius dial. Draw it properly, or trace a photo and refine it.

02

Trim, weld and interlock

Fusion-style trim, booleans and offset paths, plus Micro Trim: delete one overlapping line at a time to interlink shapes into clean, woven forms.

03

Draw at print thickness

The brush is the wall. Pick your thickness and every stroke is drawn at exactly the width it will print, centred, inside or outside. No offset lines, no Expand Stroke step.

04

Symmetry and repeat, live

Mirror as you draw, radial repeat, mirrored pairs, and wall-aware snapping so tiny cutters never bleed off the board.

05

A real blade, not just a wall

A tapered cutting edge with adjustable chamfer, frame supports for thin walls, connectors for inner pieces, and a detachable M5 or M6 threaded grip.

06

Checked before you slice

Print check flags thin walls and tight gaps, section analysis slices the model open, and every export is one clean, watertight STL.

See every feature

Where it gets powerful

The advanced end.

The features that take a sketch all the way to a finished piece: interlocked forms, real relief, moulds, seamless texture, and a component system for your motifs.

Signature

Interlocked and woven forms

Micro Trim turns two rings into truly interconnected chain links, figure-eights and woven motifs, and it still builds as one clean, watertight cutter.

Relief

Flat art, real depth

Relief mode inflates a flat drawing into genuine 3D, with domes, puffs and soft height across detailed multi-motif designs.

Moulds

Open-face moulds

Turn any relief into a single-sided mould with no parting line, ready for press-moulding or casting a silicone master.

Seamless

Endless pattern tiling

Build a 2×2 seamless tile and wrap it around a roller or repeat it through a stencil, for join-free texture at any length.

Components

Reusable linked motifs

Save a motif once, reuse it everywhere as a linked copy, and edit the master to update every design at once.

Fulfilment

No printer? Order it made

Send any design to be printed and delivered to you, auto-priced by size, with a copyright and trademark check.

“I couldn’t find a tool that let me actually design, not just convert. So I built one.”Elvia, Founder

Put together

From sketch to clay.

The tools are built to chain together, so a single session can take you from an idea to a finished, printable piece.

Photo to cutter

From a picture to a print

Trace an image, auto-clean it, shape it, and send it straight to a bladed cutter with a base and handle.

  1. Trace photo
  2. Shape and trim
  3. 3D cutter
  4. STL or order
Repeat and interlock

Intricate multi-motif designs

Combine, mirror and radial-repeat, then Micro Trim the overlaps into one interlaced, watertight piece.

  1. Combine
  2. Radial and mirror
  3. Micro Trim
  4. One solid
Art to mould

Flat design to pressable mould

Inflate flat artwork with relief mode, then flip it into an open-face mould for pressing or casting.

  1. Flat art
  2. Relief mode
  3. Open-face mould
Design to shop

Sketch to finished tool

Any design becomes a threaded-grip stamp or cutter, print-checked, then exported or ordered and delivered to you.

  1. Design
  2. Grip stamp or cutter
  3. Print check
  4. Order

Designing a polymer clay cutter by hand

No generative AI

There is no prompt box. Every line is yours.

Nothing is typed into existence

You can’t describe what you want and have a machine invent it. Every shape starts with your hand: your drawing, your photo, your motif.

Made by you, and you know it

This is a tool for artists who want to create their own pieces. When you sell or wear it, you know you designed it yourself, and that is worth being proud of.

One of a kind, not a repeat

No shared prompts means no lookalike designs. Your pieces are yours alone, not a variation of what everyone else is generating.

Membership terms

Cancel a monthly membership anytime. Annual memberships are one payment for 1 year and do not auto-renew. When a paid membership ends, your account moves to Free and your saved designs stay in your library. 3D output and export unlock again when you rejoin.

Commercial rights are active only while your Usta membership is active. If it lapses, commercial rights end immediately, with no grace period.

Free STL files are available separately on MakerWorld and are not part of any membership.
