I redesigned the oil bunker as a "kit" that I have to glue together. The purpose is to make sure the riveted sides all face "up" to make them come out smooth. It will take about 15 minutes to glue together and should look quite nice.
I also modified the gearbox so space out the gear axles a little bit more, but it is still too tight! GRRR. 3rd times a charm, right? One problem with 3d printing is that the parts aren't 100% dimensionally true. Many methods are close enough for modeling purposes, but when you are trying to get gears to mesh well it can be a little trial and error. I think that may be what happened here - the axle holes are about 0.1 mm too close together.
