The figure sheet

One angle, or every side.

Both come with a numbered figure sheet. The Design Set's sheet is made from your 3D model, so it shows every side and how the parts come apart.

If your model needs a fix first, we'll tell you and show you what to change.

Built for your shape

Five ways to build, picked for you.

We read your sketch and parts list, pick the build that matches it best, and show you which one we used and why.

How your model is built
Design Set · $39.99
Measured parts
Boxy, engineered designs with flat faces, slots and catches. Choose “Guide me” to check each part, or “Build it for me.”
Included
Drawn shapes
Round products like lamps and bottles, each part drawn as one smooth shape.
Included
Soft shapes
Shoes, grips, wearables and other cushioned things, built from rounded forms that blend where they meet.
Included
Soft surfaces
Jackets, gloves, bags and tents: a thin fabric layer over the shape it wraps, with seams and pockets.
Included
Freeform
One flowing, sculpted surface, like a mouse or an ergonomic handle, carved from your sketch’s own outlines.
Included
Easy editing
Move, resize and nudge parts, accept suggested fixes, change fabric thickness. Edits are free and every version is kept.
Included
Clothing is a 3D look-and-fit model, not a sewing pattern

What you can do with them

01Pitch it to a friend, a partner or an investor.
02Print a rough model to hold in your hand.
03Brief a patent drafter and pay for fewer rounds of revisions.
04Show a manufacturer what you mean.

What this is not

  • Not a formal patent drawing. The USPTO has strict rules for those, and a drafter can prepare them starting from yours.
  • Not a patent application, and not legal advice.
  • Not a judgment of your idea. We don’t score it. We draw it.
  • Not a subscription. You pay once per invention.

What happens to your idea

Stored privately

Your description, photo and drawings sit in private storage with no public web address. Downloads use short-lived links.

Never used to train AI

What you send is used to make your drawings and nothing else.

Drafts you don’t pay for

Deleted after 7 days. Nothing is kept unless you sign in.

Yours to keep

Everything made for your invention is yours to download, share and use.

Questions

Yes. Download the STL and open it in your slicer (Cura, Bambu Studio, PrusaSlicer) for a rough print you can hold. Sizes are estimates, so check it in your slicer first.
