Hole Blocker 5mm

A hole blocker (5mm hole) which can be adapted and re-modelled to fit any sized hole. It makes your old holes tidy and (with glue) will make them waterproof. You can buy them in the UK from Toolstation for £2.99, but by printing your own, you can make them to your own specification. I have the fds file, but the system won't let me upload it.
