My AER9 laser rifle prop (Fallout 4). I decided last-minute to make it to go with my Elder Maxson cosplay, and I spent seven hours building the framework before priming and painting. It’s made of 5mm and 3mm craft foam, a pill bottle, toothpicks, a small plastic tube, a plastic handle I broke off a toy wand, and jacket buttons. The whole thing is freehanded and held together with hot glue; the toothpicks help to reinforce the thinner pieces. Total cost of materials: $6.
