This is designed for Sotabeams lightweight antenna wire with a covering of heatshrink to protect the cable.
I use 2mm bullet plugs for connecting wire, which are really cheap and found online with retailers like ebay, aliexpress.
Slots to allow a small cable tie to fully secure, although i have found thats not really required as their is enough grip on the wire.
Sotabeams lightweight antenna wire is 0.22mm² total conductor CSA (cross sectional area) - approx. 24 AWG with outer Cable outer diameter 1.2mm.
The Freecad files are enclosed so you can adjust.
