Transformers Jetfire Arm Guard Bracket

I lost the pieces that snap onto the end of the arm guard armor. Print will supports and enough walls to make solid.

This piece pushes onto the circular stem. The best way to get the correct fit is to push the bracket onto the stem lightly, then press turn it upside down and push the bracket into the armor using the top of a table surface. This will push it flush and not too far in.
