These things are prone to coming loose, so this design makes it possible to replace any that you are having problems with. There are three sizes to cater for differences in hole diameter, but you can use scaling to get the fit you require.They may work satisfactorily by tapping them into the hole, but adding superglue may be a good idea to make them stay in longer.Print them in two halves and glue them together to get the best alignment of layers for maximum strength.
