Micro Dumper by blecheimer Oct 20, 2012

Featured Thing!

Description

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...


EDIT:
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.

Right, this will break immediately.
Try it - just rotate the stl-file in your slicer.

The only problem with orienting them that way is they are too brittle and break easily. It might be nice to have the option of printing them that way if someone desires it though.

It might be a good idea to orient the pins upwards so the base comes out round.

Instructions

1)
Print
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).

2)
Glue the dump lever to the dump body. There is a marking for that under the dump body.

3)
Assemble all parts.

4)
Build a whole fleet.

Are you planning on making anymore of these types of vehicles?  It would be cool to have a complete set of "Micro" construction trucks.

I am already working on the next one. But I need a few more days to finish it.

I made one, but I had to drill out the wheels with a 1/8" drill bit to get the pins to fit through them.  I used the chassis with smaller holes and pins fit in nice and snug.

 I can upload some wheels with a bigger hole this evening.

Very nice! Printed one normal size and then another at 2x the size. My kid is begging me to print a 4x one, maybe today :)

The only problem in both cases was the fitting of the wheel axes to the main body which is very loose. Maybe the holes in the main body part could be made slightly smaller?

Nice work!

 Thanks for your comment!
It is quite difficult to find the right hole diameter. I printed five chassis to match the holes to the axis regarding the shrinkage of PLA.
I uploaded a second chassis which has slightly smaller holes (-0.15mm). Maybe you can give it a try.

Another solution could be to print the axis at a larger scale - maybe 102%.
