Wobbly is a awesome slope walking robot. Original design (and the rest of his design files) http://www.thingiverse.com/thing:170932/ This is just his replacement head with eye sockets and eyes. Leave some brim on the eyeballs and press them in and rotate later (should probably glue them if you have kids) Maybe half print an eye and glue a spring in ;)print head 10% infill, WITHOUT brim to allow some lifting at corners - he will have a smile when attached to his body :) (or sand the corners up) Eyeball(rod) 100% infill, was done in Crystal clear filament at slow speed to ensure opaqueness, leave some brim ON if not gluing in place. Cornea is just black 3mm filament pushed in and sanded back **Note on body: print with at least 30% infill and if using slic3r UNTICK "only infill where needed" or shoulder rod will be too weak/deform/lift. 10% infill was enough for arms and legs. YMMV
