Description

UPDATE 2021.04.09: I updated the fan shroud to be better, and also added screw holes in the top of the heatsink to secure the hotend better. I updated all the files.

Based on Cadmium's original Mosquito adapter (Link below). I had to modify it a bit so it fits the slightly different heat block of the NF-Crazy hotend. More info about the build (in Hungarian) here:

Comments are welcome.

Materials and methods

At last I printed it from PC because PETG was not enough heat resistant for higher temperatures. 3 perimeters, 20% infill, no support.

Printed the fan shroud from PETG, seems to be working fine.
