3d printed the turtle neck, ID badge, pen and head. Shaved down a mobius body to remove the collar and buttons and added the printed turtle neck. Replaced the brown suit arms with some spare white ones so I could save some time painting.

and for the coat I cut 3 of the buttons off egghead's coat and glued them to the otherside and glued it shut so it looks like hte jacket was buttoned up. Since egghead is on the large body suit mold it had plenty of room to stretch shut over the standard smaller suit.
