Designed this model as an alternative to the Belink F1D008 mount, because I could not find any of them anymore. It was specifically designed to fit my F1DN204KVM-UN-3 and my not work with other versions switches (especially the shorter variants). 

It is designed to be mounted with #8 flat head screws, but an equivalent metric screw should also work. Intended to be used to mount the KVM on the bottom of a table.

I recommend printing the mount vertically (minimizes the need for support and force will be applied against the layer lines when mounted). I used 35% infill with 4 layers for walls on a .4 nozzle. The tolerances on this leave some room for play, so it can also likely be printed with a .6 or .8 nozzle without any issue.
