I build Gundam Models and had to custom make power cables for my 1/60 Gouf Flight Type since the originals came as fixed resin casts. A 4mm inner diameter made fitting styrene rods into the ends a breeze, and the outer diameter fits almost perfectly into the green cylinders, just need to run a 13/64 or 5mm drill bit through them to make just enough clearance after you cut off the backs.A niche use to be sure – but was exactly the thing I needed and it looks great even with just a test fit.
