Super B grain trailer. This is a very simple model. Components will need to be glues together.

The tires are printed in TPU which helps keep them silent.

For axles, you need a pin or something that will fit tightly into the holes in the rims. I used the spent end of 1/8 inch pop rivet.

For hitch pins I used the “rivet” end of a pop rivet and inserted it before gluing the top and bottom together.
