Visio Stencils for various ranges

I gather from searching previous topics that Visio Stencils are available and being shared via private message. I need to present a network design to the Department for Education for a school project specifically using Zyxel kit, and would prefer to present it as cleanly and accurately as possible with stencils for the XGS3800, XGS2220 and XMG1930 models, rather than having to use product photos. Would it be possible to have these, please?
