Here is an abstract nested design that ended up looking like a space family after printing and finishing. It comes apart and reminds me of an abstract... mother, father and child. It also reminds me of those nested Russian dolls.
3d model print parameters
I used ReplicatorG to prepare the file, a MakerBot Replicator2 with the Replicator 2 slicing defaults and the following settings with white MakerBot P...LA to do the printing: Infill = 10% Layer Height = 0.200 Shells = 1 Feedrate = 40 Travel Feed = 55 Temperature = 220 I used a raft with full support. It took 2 1/2 hours to print at 50 mm tall.
