A small USB charger for your Pebble Smartwatch.
Did you lose your original Pebble charger cable? Or do you want an extra charger, just in case? You can have yours in less than 1 hour! After printing you only need two pieces of metal wire. I took mine from a single-core jumper wire and used tweezers to put them in place.
Instead of using magnets, this charger snaps nicely on your watch. The design is 3D printer friendly.

Update: I added a file for the Pebble Steel. This is still experimental and needs to be tested properly!
Orient the part in your printer as illustrated in one of the images, it was designed to be printed this way. A support structure is not necessary, while a brim helps to prevent warping.
For the connectors: you will need a metal wire that is flexible enough to shape it nicely, but rigid enough to maintain its form in the end. I found that single-core jumper wires do this job just fine. To put the wires in place, you will probably need some tweezers.
Two important notes:
I found that the DIY USB plug works very well. However, as with any non-certified plug, there is always a risk of damage to your equipment. Please be careful and use at your own risk!
Before using, check your print for any sharp edges, especially on the side opposite to the USB plug. Burrs or sharp edges might slightly scratch the plastic housing on the right side of your Pebble.

Update: I added a test file for the Pebble Steel. The design is quite different from the original and needs to be tested. The design for the Pebble Steel is still work in progress.
