Robin belt buckle 66

I've been working on Halloween costumes. These are designed to slide into the center of the belt with Velcro used to attach the belt in the back. The Cylinders on the utility belt are wooden dowels 7/16" diameter by 1 7/8" long attached with short screws through the belt leather.
I rave recently added a 3D pritable dowel to this project. It has the advantage of sliding onto the belt. It also has a rounded top and bottom
