Bathroom Sewer Lid

thingiverse

I needed a cap for my syphon in the basement to eliminate its foul odor. The bounding box is 139 by 139mm, the outer diameter of the lip is 145mm, the diameter of the dome (where it empties into the sewer) is 138mm, and the entire cap is 35mm tall. The print fit perfectly, the handle makes removal of the lid effortless. The dome features some extremely steep angles at its apex, but one can still print it without any supports. It may appear a bit disorganized, but hey … it's not an object meant to be visually appealing.
