Usable for the PoE variant of the KeepLink 2.5Gb switch. Note that the non-PoE switch is slightly smaller and probably won't be compatible with this.

Simply print (both variants, L and R) and screw them into the empty holes using M3 screws (optimal length seems to be 8mm, but anything from 6-12mm should probably be ok). The holes for mounting are M4.
