Summary

This is a printed version of a classic wooden toy.
The toy in the photo is from an art show (sorry, didn't include the Mythbuster's version) and gives you an image of how the basic setup goes. It's easy and fun to make!
For the limb attachment, use a common straight pin, clipped, and bent over. The limbs should rotate without hesitation, and if they don't, drill the holes a little larger.
To string the acrobat to the frame, line the assembled body upside down to the frame and loop the string through as in the photo. Any rigid string will work (I used upholstery thread). Over tensioning the string will not allow the body to hang freely, so don't pull it too tight!
The bio hazard stand only works with the gunframe, the simplethick has no stand. You should flip the bio hazard stand over to print it, sorry, saved it wrong. You can mix and match the body parts as you like, some have bite marks because they were attacked by zombies.
Have fun!
