3D model description

Note that this part has been superseded by V2 (http://www.thingiverse.com/thing:124237)

This is a replacement annular cooling for the Ultimaker nozzle. The original cooling shroud, although functional, can sometimes be counterproductive. The unidirectional nature of the cooling stream can sometimes lift the first layer, especially when printing on a raft. The annular cooling nozzle is aimed at the printed object from all directions, thus cancelling any possible lift.

This is a replacement annular cooling for the Ultimaker nozzle. The original cooling shroud, although functional, can sometimes be counterproductive. The unidirectional nature of the cooling stream can sometimes lift the first layer, especially when printing on a raft. The annular cooling nozzle is aimed at the printed object from all directions, thus cancelling any possible lift.

The whole assembly is secured under the cooling fan, therefore avoiding contact with the hot aluminium plate which can easily distort PLA part over extended time.

Make sure to print all parts with flat faces on the platform.

You will also need the following:

2x M3x20mm bolts

2x M3 nuts

2x M3 PCB spacer

Align notches and glue all parts using super glue. The use of super glue accelerator is advised.

File bolt holes using a needle-file to allow M3 bolts to pass through comfartably.

You may have to untighten the hot end's long screws to rotate the heating block so that it lines up witht the diameter of the nozzle, otherwise the cale of the heating element will interfere.

Slide assembly in place under the cooling fan through the innermost prodruding long screws.

Retighten the long screws before securing the assembly in place using 2xM3 PCB spacers. Secure the rest of the assembly to the fan using 2x M3x20mm bolts and nuts.

The attached photos show the first iteration without the alignment notches.

I ran the Ultimaker for more than 5 hours printing an object and the nozzle doesn't seem to be afftected by proximity heat from the heating block so far.
