This is a half-size version of Stefan's double-size minifig, with added attachment posts – you may have to shave the posts to get them to fit.Print with a raft and exterior support.The pieces should all fit together without any extra hardware. You may need to widen the joint holes or shave the posts a bit, but a good tight fit is best, and a bit of mushrooming on the posts will also help lock them in and provide friction to hold the limbs in position.If you print more than a few of these little fellows, be sure to print one of the large ones too, so you'll have someone to settle disputes and provide moral guidance.
