UPDATE 29JAN2018: v3 - Fixed 2 minor issues to make the part better.
- Better centering on blower ducts to nozzle
- Added clearance from part to the x axis carriage near blower screw
If v2 is working, no need to make v3.
UPDATE 24JAN2018: v2 - Redesigned to be a thinner version, no thicker than the OEM part. Also eliminated the threaded metal inserts to get the blower as low as needed.
This is a remix that is made for the Bondtech Extruder for Replicator 2 Single Nozzle.
It also allows for fan directly pressed against the fan, to keep the 50mm socket head cap screws in place, as the Bondtech extruder has a deeper cold block.
Works with the https://www.thingiverse.com/make:145303. The downward blower is centered on the nozzle in X & Y.
No supports needed. Print from stong material, like PETG or HTPLA.
