HC Diana muzzle

Muzzle ring for HC Diana nerf blaster.  Uses 4x M2x4mm countersink machine screws, as it was the only M2 I had on hand.  130 motor screws, which are M2x5mm should fit as well.  So the choice isn't that bad, although it may not be as aesthetically pleasing as some other screws.

Tolerances are tight on this so either some fidgeting and fitting will be required.  Or even a slight remix.  If you do, please post.

I printed at 100% infill, 0.16 on a raft and it worked fine.  Since its such a small part, higher that standard quality is probably better and I did a raft to prevent some shrinkage problems I was having.  YMMV.
