1:48 Telephone/Telegraph Insulators - Ver 5

From O scale Telephone/Telegraph Pole Insulator Evolution : I made a fairly large connecting-sprue as shown.

The 0.38mm/0.15″ hole passes completely through. This size hole would let the insulator sit on a 0.015″ wire pin. I like this because the pin would be near to the full-scale 1/2″ dimension. I am pretty sure I can get a 0.38mm/0.015″ hole printed – not so much a 0.25mm/0.010″ hole.

The 1mm O.D. is enough to give us 0.31mm walls – which is a slight padding to the 0.3mm minimum wall thickness for FUD/FXD.

The idea is that you take a X-Acto knife and slice the insulator off of the sprue at the base of the insulator. I suspect the knife needs to be sharp as a dull knife might collapse the pin hole. Most likely you will need to ream the hole out with the appropriate size drill to clean up any reside .. also any support wax.
