Sleipr turns your brief into a canonical design record and a watertight STL — designed by an AI engineer, revised in plain language, approved by you. Draft free, download on a plan, printed part in the mail.
No card. No CAD. One email when your slot opens.
Name, intent, hard numbers, acceptance test. Attach a sketch if you have one — numbers win.
The AI engineer returns a design record and a watertight, printable STL — usually under 90 seconds.
“Widen the base 20 mm.” Every rev is a readable diff. Approve when it matches your intent.
Download the STL and record on a plan, or get the part printed in PETG and shipped — EU-wide.

The record is the product. Meshes are projections.
Every part you draft is a structured design record — intent, numbers, geometry, acceptance test — that survives revisions and outlives any one file format. Upstream of CAD, never against it.
