Sorry, I don't. But I think it could be modified pretty quickly to do it. I'll see if I can't knock it out when I get a chance.
If anyone downloaded the files when I first posted them, I added an stl file for plastic spacers/washers to the thingiverse page to keep the spools in place. So I currently have 3 spools above the bot and it works great.
6 x 608zz bearings
6 x plastic washers
12 x metal washers
12 x nuts
1 x nut/washer at each end of the rod.
