This is a concrete mixer truck toy. It is fully 3d printable.

The tolerance for pieces that need to fit tightly is 0.1mm,
for pieces that need to allow movement (like screws and axles) 0.3mm or more.

Observations:

• all objects already have the intended print direction in the STL files!

• if you don't like the "built in" supports for the cabin,
  then you can find only the cabin in "cabin_your_own_support.stl"

• most of the parts were printed with PLA. only the tires and
  the mirrors were printed from TPU (flexible material)

• there is narrow and a wide mixer parts, chose the one you like

• screws... there are also "sleeping" screws STLs included
  these are printed on the side which makes them a lot stronger
  the drawback is that these don't close the holes completely...
  So use only as many "sleeping" screws if the toy is going to be
  played with, and only normal/round ones otherwise

As always, improvement suggestions are very welcome (can't promise though that I'll have the time to do them all ;) )

There are, of course, other variations of this model in the pipe...

PS: the driver is not included, it was only a temporary job for him.
