About this print

A bottle with no inside and no outside: a surface with a single side, where an ant could walk from the "outside" to the "inside" without crossing an edge. A half bottle is included to show the inside.

A conversation piece for topology, alongside the Möbius strip.

Printing and using it

  1. Print with a brim; the full bottle takes 2–3 hours at 0.2 mm.
  2. Use the half bottle to trace the surface with a finger.
  3. Pair with the Möbius strip: what do they have in common?
