Slinky Dipole Antenna

My custom designed slinky antenna. People have been making slinky dipoles for longer than i have been around, but i decided to design some parts to make assembly easier. I included a picture of the exact slinky i used. I bought mine from Walmart and it has an inner diameter of about 62mm (2.4 in).

I have 3 options for the center piece, SMA, BNC, and SO239, pick which one you need. I have not printed the BNC or SO239 models, i just stole the SO239 measurements from another model on thingiverse, and looked up the BNC online, so i cant guarantee those are exactly right.

Assembly should be pretty simple with the incuded pictures. The main picture doesnt inclue the "end crank" as i havent printed them yet. I will update when i finish and take a good picture. i used #6 screws which are about 3.3mm diameter. i just tapped threads into the center piece, but you could run a long one through the center and use a nut on the other side. the center piece has a hole on top for an eyelet if you
