LICENCE - Caffeine (CAS 58-08-2) - ready-to-print release 2026-10-28, package r19

1. THE READY-TO-PRINT MODEL (STL, 3MF and G-code)
The files advanced_no-supports/molgod_caffeine_58-08-2_R3-ready-to-print_g2026-10-28_NO-SUPPORTS_add-supports-in-slicer.stl (SHA-256 61bbb8ec736087dbfad3fb423807465294afff81c257254bf4b07e0728b97f0b), molgod_caffeine_58-08-2_R3-ready-to-print_g2026-10-28_r19_3MF-project_supports-generated-when-sliced.3mf and the ready G-code
files in gcode/ (sliced from the same model) - the molecule on its display base
with the pencil supports, cups, lettering and logo, a complete MolGod.org
design - are licensed under
CC BY-NC-SA 4.0 (Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International).

Required attribution (use this text where you credit the model):
  "Caffeine (CAS 58-08-2) 3D model, ready-to-print release 2026-10-28, package r19, by MolGod.org - https://molgod.org/molecule/58-08-2/ - CC BY-NC-SA 4.0"

Summary (not legal advice; the licence text prevails):
  - You may copy, share, print and adapt the files for NON-COMMERCIAL purposes:
    at home, in schools, universities, libraries, makerspaces and museums.
  - You may not sell the files, prints made from them or adapted versions, and
    may not use them in any other commercial way, without our written permission.
    Commercial licence: pure@molgod.org
  - A paid 3D printing service is commercial use, also when it prints to order
    for a school or a private person: it needs our commercial licence
    (pure@molgod.org). Printing the model yourself - at school, at home, at
    university or in a free makerspace - is non-commercial use.
  - When you share the files or material based on them, give the attribution
    above, link to the licence and state if you made changes.
  - If you share an adapted version, license it under CC BY-NC-SA 4.0 (or a
    later version or a compatible licence, as the CC licence allows).
  - Do not add terms or technical measures that restrict what the licence permits.

Earlier downloads: files downloaded from 22 to 27 October 2026 (text "CC BY-SA 4.0"
on the underside of the base; STL SHA-256
abfa003a846d6cc2dc4cc42ae3a849a1aea85b7c299c4bb859a32222adad0411) stay under
CC BY-SA 4.0. The current model, from 28 October 2026, has "CC BY-NC-SA 4.0" on the
underside of the base and in the STL file header.
This package (r19) is licensed under CC BY-NC-SA 4.0.
The molecule alone (NORMAL and ENGRAVED STL on https://molgod.org/molecule/58-08-2/) stays CC BY-SA 4.0.

2. OTHER FILES IN THIS PACKAGE
Renders and preview images of this model (previews/, REMOVE_KEEP.png and the
gallery on the model page) are licensed under CC BY-NC-SA 4.0, like the model,
with the same attribution. The data sheet, reports, profile and texts are
(c) MolGod.org, all rights reserved. You may use them to produce, inspect and
document prints of this model under the terms of section 1.

3. NAME AND LOGO
The licence covers copyright only. It grants no right to use the name or logo
"MolGod" as a trademark and does not imply endorsement by MolGod.

4. HOW TO PRINT (information, not a licence condition)
How to print this model, the settings we recommend, the evidence behind each
recommendation and the full reference list are in PRINT_INSTRUCTIONS.txt and
PRINT_METHODOLOGY.txt in this package. These texts add no terms to the
CC BY-NC-SA 4.0 licence of the model.

5. SOURCE DATA
The atom coordinates come from PubChem Compound CID 2519 (conformer 000009D700000001);
a copy of that record is in source/pubchem_CID2519_3d.sdf. That file is PubChem data, not a
MolGod.org work: sections 1 and 2 do not apply to it, and this licence does not
change the notices that apply to PubChem data. PubChem, NCBI, NIH and OpenEye
(OMEGA) are named only as the source; they have not reviewed or endorsed this model.
