Grommet
thingiverse
Simple customisable grommet. pick the required dimensions and get your STL file, so much fun to be had. you can customise: * Flangers diameter * Flange depth * Peg diameter * Peg depth/length * Clearance hole diameter If the clearance hold diameter is larger than the peg diameter, it is omitted, so you have a bung. The flange can be smaller than the peg, not sure why but someone out there would want it.
