3D printed in matte translucent plastic that showcases fine and intricate details.
'O'/027 - 48::1 scale Dwarf B&O CPL, two pieces, front and back, are attached by sprues to make a quantity of 3 signals. This model is slightly larger than the prototypical design. The model head design is 19.2" O scale, while the prototypical design is actually 15 1/2". The reason for this discrepancy is due to the thickness of the lamp hood which by Shapeway's guidelines must be 0.3mm minimum thickness. If someone was willing to make .007" thick brass tube hoods, I could make this design closer to the prototypical design.
The model is designed to use 0805 SMD LED's. There is a 0.9mm x 5.4mm slot for wire routing through the base of the signal. The size of these LED's (2mm x 1.25mm x 0.8mm tall) and this model (signal head ~1/2"in diameter) are very, very tiny and assembly is going to be tedious and possibly difficult. Therefore this model is not recommended for novice modelers.
