So today I’ve successfully assembled my first 3D - Printed GRS TR-2 Triangular Colour Light.
It has four separate pieces that are resin 3D printed, the light box, the front background disc, the rear cover/door & mast bracket.
The LED’s are all colour correct to AAR standards, and are 0603 LED’s with magnet wire, the lenses are acrylic light pipes, these are HO scale.
