Tis true, as an experiment to see how well simply printing my 6mm stuff at 50% the size worked, I tried it with my 6mm train.
It came out so well I have released it for sale.

If there is enough interest in this (sales) I will do some of my digitally mastered vehicles in 3mm and try them too.
I will make the 3mm versions of my 6mm vehicles, single piece resin models, which will mean some slight alteration of the weapons from their 6mm big brothers in order to make them cost effective to produce.
But they will still clearly be smaller versions of them.

Anyway, all aboard the EZ Train!!
