water cooling e3d v6

this was done for a 3D printer with closed walls. The high temperature interfered with the qualitative passage of the thread through the hotend.the unit requires:2 rubber rings 2.5 mm thick for radiator, I took 15mm inner, but can be up to 20mm, a silicone hose with an internal diameter of 4mm, a water pump for the aquarium and 4 screws m4x40 with nuts and sealant. The sleeve should be made 2 pieces and glue on in the rear part of the block.
update: I added an overlay so you can install additional hardware on it
Update 2: Added holder for 5015 fan and cooling for printing
