Due to the recent incidents (things appearing on ebay) I just want to make something very clear:
I do not allow any commercial use of my STL-files, my designs and my photos!

I like small things. And I like vehicles. Why not combine both and make a very small dumper? The Micro Dumper I designed is 25 x 20 x 17 mm (1 x 0.8 x 0.65 in).

I was curious if my Ultimaker can print such a small object…


I added a chassis with smaller holes for the axis. Try this version if the axis are sitting too loose in the chassis.

If the wheels are sitting too tight you can try the new version with bigger holes.




1x chassis (or 1x chassis with smaller holes)

1x dump body

1x dump lever

1x axis

1x wheels (or 1x wheels with bigger holes)

Instead of printing the axis you can use a piece of 3mm filament. Take a lighter and heaten up the end of your filament. Press it on a flat surface to get a collar. Cut your new axis pin to 9mm (0.35in).


Glue the dump lever to the dump body. There is a marking for that under the dump body.


Assemble all parts.


Build a whole fleet.
