This is an example printed electronic, using the solder-free 3D-PCB libraryhttp://www.thingiverse.com/thing:21975
It is an LED flashlight, made entirely out of printed parts and 4 lengths of conductive thread, plus 2 batteries and 4 LEDs.
Detailed instructions for buildling this, as well as for using 3D-PCB in general:http://www.instructables.com/id/3D-Printed-Circuit-Boards-for-solder-free-printab/ , as part of the Make-It-Real Challenge (so your vote would be greatly appreciated!).
Note: If you are thinking to build, I suggest first test-printing the electronics_top, along with a switch_toggle and a peg_cap. I haven't tested it on many printers, and these pieces have the finest tuned tolerances

Tools and Materials
Currently, it has only been thoroughly tested on the MakerBot Replicator, with ABS plastic. Support for Up! soon (but the different tolerances prevent immediate support).
I have tried several types of conductive thread, and the best so far (by a wide margin) is:http://members.shaw.ca/ubik/thread/order.html
Print using the standard replicator defaults or equivalent, with no raft or support:
1x electronics top
1x electronics bottom
11x peg caps
4x 5mm LEDs, you probably want white
2x AAA batteries
4x conductive thread -- 2x~12in, 2x~18in
The uploaded drawing shows how to wire up the circuit; Detailed wrapping instructions can be found on http://www.instructables.com/id/3D-Printed-Circuit-Boards-for-solder-free-printab/step4/Useful-Example-3D-Printed-LED-Flashlight/
