FLSun V400 CPAP Duct

With hardware (4 m3x8 SHCS) this solution should weigh roughly 13 grams. I designed it with the attributes of polycarbonate in mind.

 - I have only printed it in polycarbonate - If you print it in another material please let me know how it works out!

You'll want to print it with 3 perimeters, 3 top and bottom. 15% Gyroid infill. I used hybrid tree supports from bed only with a brim. The gaskets are printed in 95a tpu and are optional.

I suggest screwing the Upper Duct to both Lower Ducts with the gasket before installing on the effector. It has to be carefully stretch around the extruder to do this. The screws thread into plastic just to save that little bit of weight as opposed to inserts.

Happy printing.
