Wrench for Planetary Gears

I liked the planetary gears fidget, https://www.printables.com/model/232551-planetary-gears-fidget-print-in-place but my printer settings were off, and mine was basically a coaster, and wouldn't turn. I hated to give up on a 14 hour print, sooooo, I thought, maybe I could force it to move if I had a wrench that fit perfectly into the middle. It worked, and so I made it a little smoother with a finger hole. I put the scad file in so you can mess with it if you want.
