Geeetech

I've got a geeetech A20M few days ago and while I had some successful 1 color prints I'm having bug problems when I try to print with 2 colors.

For first I tried to print a 2 "mixed colors" (I mean without color cleaning) dog which was a basic gcode built for the machine... It just worked.

However ...

When I think about getting a 3D printer, I can imagine dozens of toys or knick-knacks that I could create with it. But with current printing tech, I have a harder time thinking of utilitarian objects.

What useful stuff do you 3D print at home, or plan to 3D print? Office supplies? Zip-ties ...
