This is a plug that goes in each end of the bottom rubber weather stripping of a garage door.
Measured and copied the plugs that came with my replacement weather stripping as I needed two more.
25mm diameter at the bottom. Will slide into 1" holes.
Best printed in TPU! I printed mine with a .4mm nozzle, 3 walls and no infill.
