The Arachnotron. Killer boss from Stage 9 of Sky Force 2014.

Updated with the addition of a removable top gun, for extra boss action.

Parts needed:

Leg 1 - quantity 4, no supports or raft needed.
Leg 2 - quantity 4, supports needed.
Leg 3 - quantity 4, no supports needed.
Leg 4 - quantity 4, supports needed.

I printed this with 30 % infill except for leg 3, which tended to break so I used 50% infill. I used 3 perimeter shells for the head.
