Lego Big Boy Drive Rods

These drive rods are specifically designed for my Lego Big Boy model, however they can also be used on other locomotives.

More info on the locomotive can be found here: https://reb.li/m/89126

!!!BEWARE!!!
There are 3 different versions here; "exact", "+0.1" and "+0.2"
Before printing any parts, print out the Precision test in order to see your printers/filament capability's.
By checking the fitment with lego pins and axles you can determine what version to print.

For the Big Boy all parts need to be printed 4 times, BUT the "Valve Timing Bar" needs to be printed twice mirrored and twice normal.
