Now you can make your own plugs if you have a lathe. Just mill aluminium caps and cut the heads from releasable zipties and you are good to go. All I can say that it is at least 2x more easier and faster to install than regular zipties. Looks arent bod either?

Soon that kind of caps can be bought from Tuneko/me

That plastic tool costs 8000€, which is too much so have to start with these two piece versions.
