It's a cap for a pencil
This was designed to be a showcase piece and logo for Cymon's Designs ( http://cymonsdesigns.blogspot.com/ ), however the wordpress template that I'm using won't allow me to use an image. Ah well, it's still a cool print. Every letter showcases a different challenge. Overhangs, fine details, and bridging, as well as others are present. It's designed for printers with .4mm nozzles. Print double sized for an assured successful print. From the side it's some strange alien landscape. From above its a logo.
