Printrbot Play Fan Shroud For Ubis 13 Hotend

UPDATE 12.22.2015:
Replaced the old 10 degree shroud with new 5 degree and 0 degree ones.
The last design is quite unusable because I forgot to account for the ramp of the fan mount. Oops.

I found Ubis 13 hotend is a bit longer than ceramic Ubis hotend. So I made this fan shroud to direct the airflow to a lower point, where the material is cooled, instead of the nozzle.

Based on the dimensions of tnsi's design.
