About this 3D model

I got a request for a dragonfly mold. The requestor mentioned using feathers for the wings and attaching them to some hole(s) Instead I designed the fly with some rods to tie the feathers to using string or glue (orboth) Or depending upon the scale, use small dowels (toothpicks?) and put them in the rod part of the mold, cast and remove them to leave holes in the fly. intended for use with oogoo (sugru cheap alternative) fill each side with rubber and clamp the halves together. (this version has slots on the side for rubber bands to clamp while curing) scale as desired.
