This is a 10 inch rackmount for various branded 4 port KVMs including TEETEK / GREATHTEK / PWAY and others..

This prints diagonally on the bed and fits a standard Ender 3 / i3 bed with it's print size being 208x208, print face down as provided, if you have a larger bed then rotate by 45 degress.

It slides in from the back (due to the feet), I've used double sided tape to secure and it has a beveled front as I have wrapped mine in vinyl wrap (photo is a work in progress project)
