This is a re-working of the Main Frame of the 1st Generation Cyclone PCB Factory. It is split into two pieces so it is printable on a Printrbot Simple ( or other smaller bed printers. )

The Cyclone PCB Factory can be found here:

To use this you will have to load each of the sides, split the object and delete the one you don't want to print. I left them as a single object to try to reduce confusion.

I then use a Nut & Bolt to strongly join them. I may fuse them with Acetone at some point. I am successfully using these on my Cylone PCB factory.
