Energy Dome / Devo Hat

thingiverse

http://en.wikipedia.org/wiki/Energy_dome The inner space is formed into an inverted pyramid to eliminate overhang problems and also to please a colleague who thought it would look more appealing that way. For anyone who'd like to experiment, I've included the ipt file as well. The STL design features a 10" wide hat at its largest diameter, however my printing limitations allowed me only for print this section across six inches, because of a lack of enough free space in my print area. Luckily, this scaled down size happens to fit nicely on a particularly grumpy feline.
