3D printing

Print a duck with the code built in.

No marker, no sticker. The QR and the duck's five-character code are printed into the base, and quacktrack.net is cut into its side. Every file carries a code no other duck in the world has.

  • A Bambu 3MF, ready to slice. Already at printing size and already painted for the AMS. Drop it in, slice, print.
  • Its own code. Reserved the moment you ask, and yours alone.
  • A page of its own. The duck appears on the map the first time somebody finds it and says where.

One duck per file, because each one takes the best part of a day to print and every code handed out is a code no other duck can have.

What you need

  • A printer with more than one color. An AMS, MMU, or anything that can change filament mid-print. The QR is read by contrast, not by depth — printed in a single color it is unlikely to scan.
  • Four filaments, or fewer if you don't mind a plainer duck. Body, eye whites, pupils and bill. The QR shares the pupils' spool.
  • About eight hours. It's a solid little object, and it is printed at a size that scans rather than the smallest size that fits.
  • A smooth plate, if you have one. Textured works. Smooth gives a flatter first layer and a crisper QR.
