1/8 scale caboose

CREDIT:
I borrowed the trucks from here: https://www.thingiverse.com/thing:2165853

NOTE: i edited the trucks so that they would fit together easy, the original has NO clearance and most print heads are .4mm thats 16 thousands of an inch, 8 tho on either side of your designed line, therefore you must leave at least 0.008 inches on either side of an object for press or slip fit parts. i gave you total 250 thousands but remember this is in 1/8 scale so scaled down it works out fine.

Otherwise i designed it in sketch up based on an N scale model shown in the pictures.

the file provided is an exploded version IN 1/8 SCALE you will need to scale it down, (i did 0.15 for the model shown and it ended up O scale but 0.166 would be the correct scale to O scale) and then split it up it into parts in your slicer, I use cura and i right click the part and select "split object into parts" everything you need to print will be there.

Enjoy.
