This is an accessory which can be used to mount a Dell dock / port replicator to the Hexagonal Storage Wall from rostap. It works with the following docks that I have checked, though it may also fit more:

WD19S

WD19TBS

WD19DCS

The mounting holes are set to the corners of a 63mm x 63mm square. The docks themselves have just 2 holes, however the inclusion of 4 in the mount allows it to be rotated to suit the orientation of your hexagonal wall. I have incorporated the same inserts from rostap's original design, there are 4 of them as the docks can be quite heavy.

You will need 2off M2.5x10mm cap-head bolts to fix the adaptor to the dock, which can then be pressed on to the wall, the depth of the plate allows the cap-heads to be flush with the plates underside and allows your fingers to access the ports easily.
