Settings: MakerWare custom profile in about 45 minutes before everything suddenly shifted four inches to the left and we made a pile of angel hair plastic. Settings as used in Day 5 except with shell thickness and roof count of 2:
"numberOfShells": 2,Technical notes: I got the icosahedron from johnchris' icosahedron Community Shape Script on Tinkercad, which meant that I had to rotate it to get it to sit on a face instead of a vertex. In Tinkercad it can be difficult to get things to rotate to just the right position to lie flat on the build plate, so to compensate I added a couple of wedges to the bottom to flatten things out. Stay tuned for a future full print of this icosahedron once the Replicator 2 is repaired.
UPDATE: Check out Day 32 for a successful icosahedron jawbreaker trap!
