I wanted to print the Eiffel Tower model large. Starting with the 4-part files (from http://www.thingiverse.com/thing:32825 ), all but the bottom piece could print at 350% on my Replicator 2. To print the bottom part I had to cut it in half using Blender ( http://www.blender.org/ ).
At 350% even the railing prints at a .1 mm layer height. RepG kept crashing right at the end of slicing the bottom halves so I ended up using MiracleGrue for those pieces.
I printed the bottom halves upside down so the main arch isn't a giant difficult bridge.
Print times (top to bottom):
EiffelTowercut4_fixed @ .1mm: 5 hours
EiffelTowercut3.2_fixed @ .1mm: 7 hours
EiffelTowerCut2_fixed @ .1mm: 21 hours
EiffelTowerCut1_halved @ .27mm: 5 hours x 2
Total build time: 43 hours
Total weight: 338 grams
Total height: 41.5cm / 16.3 inches
