1986 Nerf Boomerang Grommet Weight

This works.

Have an old Nerf boomerang missing the weight inserts? Now you don't.

a dab of super glue or epoxy around the male end. press together, wait 10-15 minutes. done. no raft, no supports needed. I would use 15-25% in-fill. Or change that to alter the way your nerf boomerang flies.

cheers
