N Scale Working Semaphore Signals

Wishing your static semaphores had some movement? These will help give the all clear.

This will allow you to make several types of semaphore signals in N scale. The Arduino sketch allows these to operate as three and two position semaphores in JMRI. These will likely scale up quite easily as well for larger scales. You'll need to know your printer and slicer settings well and have the printer dialed in for fine details. The spectacles are only 0.30mm thick as you'll sandwich two to together with a clear piece of plastic in the middle for the roundels (lenses). These will be the hardest to print. Use micro drill bits to ream out holes.

The "Complete" file will print out a few of all the parts needed so you can get a feel for making these.

The "Wire_Bend" STL is not made to be printed but is a 3D visual reference on how to bend the brass rod.

I'm currently working on a full write up for building, setting up
