It is a conduit for layer fan, use with long extruder and fan 40x40.
The sample of the photos has a thickness of 2 mm, I can not find reason why it should be thicker.
Being made in PLA it costs a little more to remove the adhesion edge to the plate, although nothing with a good cutter
Since I am building a Cube printer, with extruded aluminum from MakerGal, a little honor to this material that is going great for me.
Overview and Background

This is the conduit for layer fan of my printer project, jejejej you can see that it is still under construction.
Lesson Plan and Activity
Designed in sketchup, upload file for modification.
Made in ABS, because being close to the extruder will withstand the temperature.
