Summary This is a insulator for covering t wire joins in 1mm electrical wire. I primarily designed these for use on my model train layout for covering the joins where I have tapped into the main feed wire. I have finally decided that those plastic tapped joins are ugly and wanted something that looked nicer. And this is it. This model has a centre cavity of 5mm to house the join, I join the 2 halves together using some thick ABS goo, in this case green. This model is designed for a cable that has a 3mm outside diameter plastic insulation. Can be scaled up or down to suit other size wires. May do another that the wires lay against each other.
