Part blower for the Ultibots Micro Extruder.

Is made with half of a circular blower, combined with M. Hackneys (sublimelayers), "Tusk" fan mount.

Built in support.

It uses one 4020 blower fan.

Edit 08-11-2017: Updated the model. Should be easier to print now.
Edit 06-12-2017: Added files for an original Tusk part cooler remixed and fitted on a microextruder. I do not consider it a final design but it's a working prototype. I'm including an STP file.
