Railway light signal - Assembly manual
Needed parts or materials (suggested, you can use other matches parts)
7 pieces M2.2x6.5 screw (DIN7981).
Printing
We recommend using PLA filament, a 0.4 mm nozzle, and a 0.2 mm layer height, but feel free to test other settings as well.
All parts are positioned ready for printing, so you don’t need to rotate them in your slicer.
The parts are easy to print and do not require supports, brims, or rafts.
Print all parts with 100% infill, but if you’d like, you can also try other settings.
If parts don’t fit on your printer bed, try rotating them diagonally. This can help especially with longer elements.
Assembly
The signal-slider.stl part needs to be painted in three colors. Oil-based markers work best, but you can try other techniques as well. It's important that the painted part can move freely up and down the structure.
To make assembly easier, the tools folder contains a file called assembly-tool.stl. This is a tool that helps hold parts in place while screwing together the signal housing.
Part fitting and testing
The signal is designed so that even prints of lower quality should not significantly affect its functionality.
If the signal doesn’t lock into place after assembly, check the interaction between signal-sensor.stl and sensor-slider.stl. When the green light is on, sensor-slider.stl should rest on signal-sensor.stl and lock into place.
If the signal suddenly stops turning off, the issue might be with the sensor-spring.stl spring. In that case, replace it with a new one.
You can secure the axis holding the switch lever to prevent it from slipping out by gluing it in place.
Two-color track printing
If your printer supports filament changes during printing, you can make the rails in a different color.
The height at which you should change the filament is 4.1 mm or higher.
In your slicer, check which layer contains only the rails. If your printer supports the M600 command, you can insert it into the gcode after that layer.
Remember or note down the layer number where you want to change the filament color! It’ll be useful for printing all tracks.
Track connection fitting
The model is protected against "elephant’s foot", but this is still the most common issue affecting proper track connections. To avoid problems, first try properly leveling your print bed.
If the track joints don’t fit well, try gently filing them with a file or trimming the connection edges with a small knife.
