As it says, it is a faithful recreation of Ant-Man's forearm bracer from Avengers: Endgame and Ant-Man and the Wasp worn by Paul Rudd. It was made in the Windows 10 3DBuilder, and it is a chiral piece, which means that if you print it for your own use, print it then flip it in either the X or Y axis and print it again. I hope you like the result, I made the Ant-Man costume and it turned out really nice. Now it is your turn :)
