E3D Kraken Compatible Platform / Mount for RichRap's 3DR or Rostock type Delta Printers

This is a ground-up remodelling of the Micro platform / actuator carriage for RichRaps 3DR Delta Printer.

This has the corner screw mount points and should have adequate clearance for all 4 of the E3D Hotends to be mounted simultaneously while still allowing the water cooling to be utilised.

While this should be the final version, is fully functional in my tests, this is technically a work in progress.
I need feedback to refine this design! Please let me know of any fault or needed modif
