roger and other designs are also available on shapeways:
I updated the pose to improve rogers balance and keep the head to bend back when using a vapor bath
I was looking for some specific alien figurine to buy...unfortunately there are none available for some reason. So I made one myself.
Printed it on my my trusty solidoodle 2 with the 0.3mm profile in slic3r, modeled with Silo 2.
It's about 120mm in height. You'll nedd to use support structures, else there's just gonna be spaghetti on your print bed.
Scale down on your own risk, the neck and arms are already quite narrow.
Use artist tape to mask the eyes, then spray this sexy alien with some gray spray (e.g. montana Black "Mouse") then paint the pupil cavities with some black sharpie.
