printed on a ender 3.

i printed it at a .28m layer height and 20% infill.

made these to use as a dual exhaust system for my 3d printer. as my exhaust only has 1 hole and my two fans are weak so i thought combining them in a pipe
would make them stronger so i quickly whipped these up. i made the t fitting first but it did not fit in the space i had. it may for you but it depends on how your
enclosure is set up. the Y fitting is what i designed second. it fits better in the area i need it to.
