About this model

We printed this one ourselves this week, on a Bambu Lab. The three photos on the wooden desk are that print: white, one piece, pencils still standing, no paint. The other pictures are renders, where we coloured the supports orange and the pencils yellow so you can tell what's what. It's caffeine, roughly 106 million times bigger than the real thing. Each atom has its letter engraved, the double bonds show, and the base carries the name and CAS number. Nice one for a class: find both rings, count the four nitrogens, spot the two C=O. Which file? * Prusa MK4, MINI or Ender-3 S1: take the G-code with your printer's name, the supports are already in it. It only runs on that printer (an MK4S will complain about the MK4 file, so use the 3MF there). * Any other FDM printer: open the 3MF in PrusaS…
