Bobblehead Windup Walker Cat
thingiverse
A less efficient employment of a 5-pack walker mechanism, but more entertaining, is demonstrated in this video:http://www.youtube.com/watch?v=LompQ0sTG28. As for the instructions, print the head with support. The Catbodyf design features a regular feline configuration with all four legs moving forward, while the Catbodyproto allows you to install walker mechanisms in either direction, though opposite motion didn't enhance the bobblehead effect. Removing mechanisms for switching directions is tricky due to tight Replicator prints. The 35mm spring pin is used for the neck, and the 75mm snake pin for the tail, both interchangeable with other parts at http://www.thingiverse.com/thing:17725 for a possible giraffe cat.
