Ten O scale Canadian Pacific tall switchstands. Each kit includes a tall base and handle, three targets, a mast step, and two Piper switchlamps, one with two 9in metal targets on opposite sides.
They are printable in:
-Smooth Fine Detail Plastic for $40.00US ($4.00US per switchstand)
-Smoothest Fine Detail Plastic for $50.00US ($5.00US per switchstand)
Smoothest Plastic is printed at 16 microns (0.016mm) per layer, so details and lettering will be stronger and more legible than Smooth Plastic (printed at 29 microns (0.029mm) per layer).
