We made this Nerf gun cabinet with 2 IKEA Besta shelf frames. The gun "holders" are acoustic foam tiles, cut to fit and the shelves are lined with thick, tool box drawer liners (to prevent the guns from slipping and scratching the wood) The color-changing lights are IKEA DIODER. We had the sticker custom made and then mounted it on IKEA's Mosslanda picture ledge. There are screw holes to attach the Mosslanda to the Besta shelf units.
