3D model description

This is a tanker-car for the OS-Railway concept.
Click here for the OS-Railway main page:

This car is based on the same bogies as the freight car chassis you can find in the following link:
But for convenience I've included all parts you need on this page so you don't have to download anything from there.

First look at the pre-assembled STL's called buildplate_something, but all parts are also included separately.

If you wonder why the main tank parts are rotated the way they are, it's to compensate for a not-perfectly-calibrated Z-axis. I noticed that at least the Prusa can suffer from a tilting Z-axis which will make the prints tilt. Even if it's a very tiny angle it will be amplified if a part is split in two and printed so that the angles adds to each other. If the parts are rotated 180 degrees compared to each other, the angles will take out each other and the tank will still be straight.

What you need:
6pcs M3x10
2pcs M3x10-12
8pcs M2x6
2pcs wheel axles 3mm x 42mm suggest carbon fiber
8pcs ball bearings 3mm id, 6mm od, 2,5mm width (or use the dummy PLA bearings included, they actually have a very low friction against carbon fiber but you may need to drill them out a bit to make the shafts turn loose. I actually used these on my prototypes to save ball bearings and this works way better than expected!)
