Thank you
ZEIM stands on the work of many people. This page says thank you to the people and projects behind it: the free tools it runs on, the makers whose models you can print, and the people who tested it. If we have missed you or got something wrong, please tell us and we will fix it.

ZEIM uses other open-source packages that these depend on. Their names and licences are in the repository's constraints.txt.
Makers and their models
Every model you can download from ZEIM's free library or Showcase is somebody's work. Each one carries its maker's name and licence, here and next to the download.
The names of the makers of ZEIM's free library will be listed here, with their licences. Coming soon.
ZEIM Originals are made by the ZEIM team and its friends; each one names its author.
Testers
People who tried ZEIM on their own phones and printers and told us what broke.
We will list our testers here by name, once they say they are happy to be named. Coming soon.
Names that belong to others
Creality, Creality K1, Creality Cloud, Creality Print, PrusaSlicer, Bambu Lab, OrcaSlicer, Cura, Shapr3D, Apple, iPhone, iPad, Safari and other product names belong to their owners. ZEIM is not affiliated with, endorsed by or sponsored by them. We use their names only so you can tell which app or file we mean.
Something wrong? Tell us.
If you made something shown on ZEIM and would like it credited differently, or taken down, or if we have missed a credit, please tell us and we will put it right quickly and kindly. You can use the Report button on any project, or contact the person who runs this ZEIM. Contact address: Coming soon.
