2-Part Plastic Sleeve for Table Umbrella

prusaprinters

This is a 2-part sleeve to fit around the shaft of a table umbrella, because otherwise it might move with the wind and bang against the wall of the through-hole.  I designed this for my circumstances:Table hole diameter = 50 mmUmbrella shaft diameter = 38.6 mmThe sleeve is in two parts.  You simply drop the parts on opposite sides of the shaft. It's not a tight fit – it's meant to be easy and quick to insert and remove – but it restricts almost all of the wobbling motion.The print is very straightforward: .30 mm layer height, 20% infill, no brim or support necessary.  I used inexpensive Inland PLA, it should be fine with anything you have on hand.
