Bathroom Sewer Lid

thingiverse

Needed a lid for a syphon in my basement to seal its bad smell. The bounding box is 139 by 139mm, the outer diameter of the lip is 145mm, the diameter of the dome (where it falls off into the sewer) is 138mm, the whole lid is 35mm high. The print fit like a glove, the handle allows for easy removal of the lid. The dome as some very steep angles at its apex, but one can print it just fine without any supports. Will look a bit messy, but hey … its not an object to be looked at.
