Plug with hole for wire
Ring for wire against drops of water going down the wire
1 Plug
I have wire going from roof to ground (for lightning protection) hidden under thermal insulation of house inside of plastic pipe of external diameter 32mm (internal diameter is 26,5mm). Wire is 8mm thick aluminium.
To prevent bugs going inside of pipe and doing nasty things there (as they always do), I created plug, which leaves no room for bug to go in.
I printed it from PETG with 0,8mm nozzle and 0,3mm layer height. Print time: 8 minutes.
One plug consists from 2 identical parts so you don't have to put plug on wire at the beginning (one always forgets).
There are two 3mm holes where you can (it's optional) put up to 12mm long stick/nail so 2 parts are lined up.
2 Ring
Wire for lightning protection should have as little turns as possible and turns should not be sharp. Any sharp turn of wire might cause additional damage to property. But is you have wire going from roof to wall following rules mentioned, drops of water will go down the wire into your thermal insulation or it will flow down your wall, none of which is good for your building. To remedy this problem I created ring that will stop drops of water. This way drops of water will fall down to ground directly from ring. This is not my idea, it is used in industry of lightning protection, but many people are not aware of it, some workers don't care for your building so they don't install them and those rings are difficult to buy, because they are so cheap that it's hard to have any profit on them. Also, these rings are usually white.
So if you have printer, just print them from suitable material and you have them in desired color for near zero price.
