If you can say it, you can print it.

For printer owners who don't do CAD. Describe the thing, tap it to adjust, and print it at your exact size: a lost battery cover, a jig for your drill, a stamp with your logo, a cookie cutter from your kid's drawing.

Download on the App Store (Apple's badge goes here: the artwork from developer.apple.com/app-store/marketing/guidelines)

Video: tap a face, say "2 mm wider", it rebuilds (to record)

Not in any library? That's the point.

Every object is made for you: the gap in your drawer, the cover you lost, the stamp with your mark. Not a download that almost fits.

How it works

  1. Say it. "A battery cover for my remote, 42 by 23 mm, with a clip on one end." Type it or say it, add a photo if it helps.
  2. Tap it to change it. Tap the part that's wrong and say what to change, or move its slider: "2 mm wider", "rounder corners". No describing it all again.
  3. Print it. Download the 3MF for your slicer, or open it in Bambu Studio from a computer. Measure once, and if the first print needs a 0.3 mm tweak, tap and say so.
Screenshots: the chat, a tapped face with its sliders, the print view (to take)

Measure once. Fit the first time.

You give the measurements, from a ruler or calipers. Sizes are sliders you can move yourself, for free, as often as you like.

Lost it. Broke it. Print it.

Battery covers, knobs, clips, brackets: the small parts nobody sells on their own.

Prints on your printer

Every object downloads as a 3MF for any slicer. On a Bambu printer, open it in Bambu Studio from a computer in one click. Figures and animals come from a 3D generator and join the rest of the object as one print.

Pay per thing, not per month

Ten credits to start, then packs of credits in the iPhone app; sliders, sharing and copying cost nothing. Pricing.
