You have seen this type of device in the movies now build your own. Average assembly time can be up to 7 hours. I know that it is long but the process is rather satisfying upon completion.
Included is an engineered build plan along with the cardboard shapes that you must cut out and assemble.
You will need to supply the cutting tools and glue. Recommended is super-glue (cyano type), glue-stick and hobby knife for cutting and assembly.
Step 1: Download and print.
The cutting of the shapes is best accomplished with a sharp x-acto type knife but scisors will do in a pinch.
You will need to print 5 of the 26Wheel file, 1 each of the remaining. The assembly7 file is meant to be printed on standard copy paper.
