Bachmann Split Chassis Axle

Axles suited to Bachmann OO and HO split chassis steam engines, to replace the feared "split axles".

One has a 2.2mm square hole, and the other has a 2.15mm square hole. The 2.2mm hole has worked for me, but you might find that you need a tighter clearance depending on the condition of the pegs on the wheels.

I recommend printing 'vertically' if using filament, to preserve the curvature and aid rolling.
