This is a 3D printed dual rackmount kit for the Ubiquiti Unifi Security Gateway and Unifi Switch 8 60W. It can be installed in a normal horizontal rack. This kit can come in one or two pieces, the one piece version includes power brick holders for the USG and Switch (it costs more because there's a lot more plastic being used along with a lot more time to print). Rack screws/nuts not included. Comes assembled. The rubber feet on the USG and Switch must be removed prior to insertion. There are catches on the back to prevent the units from sliding out.
Please note that 3D printed items will have minor differences between them and may have imperfections (the final results are never the same). This is normal and how 3D printing is. I will try my best to provide a clean and functional product nonetheless.
