nachoman 2021 do something clallenge, part 3

[nachoman]

The 3d printed parts arrived, and after looking at them I've come to realize I have some more work to do here.   The gearbox/motor mount design is fine, but looks like I did not make the axle spacing between the two gears quite wide enough.  As in maybe 0.1mm too close.  So I will tweak the design and try again.

The oil tank looks okay, but rivet details don't work well as well in this material when printed on a vertical surface.  For my HOn3 oil tanks, I printed the sides and top separately and glued together, but this time I tried all as one piece.  As a result, the sides are too rough.  This one is useable, but I either have to delicately sand the sides around the rivets, or sand the whole side smooth and use rivet decals.  But, the size is fine and the top looks great.   In any event, I need more for future tenders, so I have modified the design to print the sides and top separately and will likely try again.
