Parts to measure · STL and STEP

Pick a template. Download the part.

Adjust the dimensions or type the name and get a print-ready part — no modelling software. It comes out as STL and as STEP for your CAD.

How it works

From dimension to file, in seconds.

  1. 01

    Pick a template

    Parts anyone who prints ends up needing — plus the Letter with Name, the most requested gift.

  2. 02

    Enter the dimensions

    The fields are the dimensions that matter. Anything the part cannot take is refused right away.

  3. 03

    See it in 3D and download

    The part shows up spinning on screen. Download the STL to slice, or the STEP to open in your CAD.

What is next

Describing it in plain words, with no template.

The next step is writing “wall bracket for a router, 3 mm thick, two 4 mm holes 60 mm apart” and getting the part — with no template to pick.

TodayThe templates above are our own code, reviewed. What you enter are the dimensions, and they are validated before they become geometry.
LaterWith free text, a language model writes the code for the part. That changes the problem: it becomes third-party code running on our server, and it only ships with isolated execution.
HenceWe would rather open with templates that work than with a text box that gets it wrong half the time and charges for the privilege.

Lithophane

A photo becomes a relief to print and hold against the light: flat or curved, with a frame. The photo never leaves your computer.

Printing planned

Weight and time

Estimate filament and print hours before sending the part to the queue.

Coming soon

Modelled. Now someone has to print it.

The part comes out ready to slice. If you have no printer — or do not want to wait for your own queue — NEO 3D Print prints and ships it.
