Alternate Launcher for Dremel Devil

I couldn't get http://www.thingiverse.com/thing:266035 to launch properly, so I whipped up an alternate launcher in Fusion360. I tried a version with "hooks" on top of the arms, but in the end the best design was just straight arms.

Screw a metal screw into the bottom, then use a cutoff wheel to remove the screw head. Put what's left in your Dremel and enjoy!
