update 04/12/2014: have now printed a test bit messy on the print but need to now test fire it to make sure it flys nicely

this thing is a remix of http://www.thingiverse.com/thing:127124

I have added a little ring to the hook so you can attached a piece of
string I haven't tried printing this just yet so its a work in progress hopefully it wont over balance the hook to much!!!

These instructions are taken from the original design which can be found here http://www.thingiverse.com/thing:127124

Printed without raft/supports. The first 5-6 layers look a little rough for lack of supports but it builds just fine.

I printed:
100% infill
.2mm layer height
2 shells
60mm/s travel

but these settings are probably changeable
