Signal Box HO Scale 1/87

this is a 2 led signal box. it is suitable with 3mm leds. i printed it at 3 plates as you can see at 3mf file.
the only thing you need to be careful, put the signal box back cover vertical as you can see at the photo to keep the hole size normal for tube.
warning plate is 2 color, so you need to print it 2 color if you do not want to paint later.
