[GreenKeys] UGC-136 ribbon status update

[John Hargett]

So have tried to look at the Onshape file, and even set up a free 
account, but unable to load, doesnt matter which browser I am using and 
even did a  browser check thru onshape and says that it is compatible , 
never used onshape before, any suggestions?

Can I download the file and open in my 3d print software?
