This is a 3D printable terminator arm replica based on Terminator 1. I modified the original design to be easy to 3D print, but also so that each finger could open and close using only one spring. I did this by using levers similar to the Terminator 1 version. the wrist movement is also controlled by springs and strings. By attaching gut to a glove or motors, the fingers can easily be opened and closed. Included in this download: 1- A colour coded build guide in PDF format. 2- A mini print-in-1 version. 3- All parts named and ready to print. 4- Smoothed and unsmoothed parts. 5- Assembled arm and all parts in 3ds Max and obj format. You will need a few springs, screws, gut, wire and a lot of time, so have fun & enjoy! The base and control system is now also available to download in my products.
