The stls should load in the correct orientation and require no supports.  I suggest printing with no cooling fan for best layer bonding.  I included the step and fusion files so you can modify for your needs. 

Insulators like this are easy and cheap to buy but for the round pipe I needed something custom and I made a few screw on wood post ones just so I got the length I wanted. 

These have been in use since before 2020 and none have failed.

I printed all of these out of nylon trimmer line. This makes extremely strong and tough parts.  I bought round .065" blue trimmer line from MaxPower on Amazon.  I have printed a lot with this stuff and it makes very strong parts, though it is prone to warp like most nylon so large parts are difficult. And I make sure to dehydrate the nylon before and during printing.
