This rook from Thingiverse takes about 56 minutes to build on the Rep 2. One hour 44 minutes on the 5th Gen, not including that 15 minute pre-print overhead.



As with the stretchlet, the one from the Rep 2 is indistinguishable from the one from the 5th Gen that took twice as long to build.



Right around now the guy that owns the 5th Gen saunters into the store and I explain what I've found so far. He almost started crying. I showed him the stretchlets and the rooks and asked if he could tell them apart. The closest thing he could find was the arch over the door of the rook that the Rep 2 built had a little dangly artifact, which was quickly scraped off with an Xacto knife.
