CobbleBot Accessory Mounting Plate

I am in the process of creating my own hotend cooler for my CobbleBot 3d Printer. This is the first part to it which everything else will mount from. It replaces the retaining plate used to hold the Hexagon Hotend. I mounted my Y carriage upside down and will be designing my accessories off this configuration, but this plate can be mounted either way.

As always I have included the sketchup file if you want to make changes.

EDIT: Added a top mount version which should line the bottom of the holes up properly for my further accessories.
