Train track tunnel
thingiverse
A simple and flexible tunnel for OO gauge model trains. The tunnel is wide enough for two tracks side by side. The design consists of 3D printed ‘end’ and ‘middle’ models. These models are connected by threading 4mm diameter dowels through the holes to create a robust unit using two ‘end’ models and one ‘middle’ model. The design allows for multiple ‘middle’ pieces to create longer tunnel lengths – the one shown is 15cm long. The tunnel can be used as is or as a frame to be covered as required.
