A ready-to-print model of this molecule on a display base: rotate it, zoom in and see how it looks straight off the printer and after removing the supports.

1. Download a file
Not sure what to pick? Prusa MK4, MINI or Ender-3 S1 — take its G-code. Any other printer — the 3MF project (PrusaSlicer) or the STL (other slicers). Printing at a makerspace or print shop — hand over the ZIP package and the PDF data sheet.
Ready G-code for your printer — each file only for the printer it names. Load it and print:
Another printer? Download the 3MF project with all settings and open it in PrusaSlicer — or import the model into your own slicer.
2. Print as supplied
Base flat on the bed, no rotating and no rescaling — the file is in millimetres. Keep your slicer’s automatic supports switched on.
In your own slicer: organic (tree) supports with “on build plate only” switched OFF — every tree starts on the base (Cura: Support Placement = Everywhere). After choosing your printer, press A (Arrange) so the model sits in the middle of the bed.
3. Finish the model
Remove only the orange slicer supports. Keep all 13 yellow pencils — they are part of the model and hold the molecule up. Cut the supports with flush cutters, from the top down; do not pull or twist. The model prints in one colour — the colours exist only in the preview and in the picture below.
Panel 3 is a render, not a photo of a print — the model prints in a single colour.
Optional: want to turn the molecule in your hand? As the last step, cut each yellow pencil at its thin neck just under the sphere (about 2 mm) and sand off the small cone left on the sphere. Go slowly — the bonds are about 2 mm thick. We have not yet confirmed this step with our own print.
4. Show us your print
Send us photos of your print — with the supports and after removing them — to pure@molgod.org.
These 4 photos help us most: the whole model with supports, the finished model after removing them, a close-up of the thinnest bonds and a close-up of the letters on the spheres. Feedback is welcome, but it is not a condition for downloading or using the model.
3D printing is all about the details. If something did not come out right, send us the photos: we will help and improve the model based on your feedback. Teacher? Join Wave 1 of the pilot →
No 3D printer?
Ask at your school makerspace, a library with a 3D printer, or a local 3D printing service. Give them the print package or the technical data sheet (PDF) — it contains everything they need.
A paid 3D printing service is commercial use and needs our commercial licence: pure@molgod.org. A school makerspace, library or university that prints free of charge does not need it.
Status: checked digitally and in the slicer; we have not printed it physically yet. Your print could be the first. Print settings, files and licence ↓
